Republican Rep. Darrell Issa issued subpoenas Tuesday for a host of State Department emails and other communications on the Benghazi terror attack, signaling that the Obama administration’s recent document dump would not satisfy congressional investigators.Issa, chairman of the House Oversight and Government Reform Committee, claimed in a letter to Secretary of State John Kerry that the department is still “withholding documents.”

He demanded the department release more on the administration’s behind-the-scenes discussions, in the days after the attack, on how they would describe the strike. These documents have since become known as the “Benghazi talking points.”

“The State Department has not lived up to the administration’s broad and unambiguous promises of cooperation with Congress. Therefore, I am left with no alternative but to compel the State Department to produce relevant documents through a subpoena,” Issa wrote to Kerry.

State Department spokesman Patrick Ventrell said Tuesday that the department “remains committed to working cooperatively with the Congress” and would “take stock” of any requests for information — but noted that the department has provided thousands of pages of documents.

“We have demonstrated an unprecedented degree of cooperation with the Congress on the issue of Benghazi, engaging in over 30 hearings and briefings for members and staff, and sharing over 25,000 pages of documents with committees,” he said. “All of us — in the administration, in the Congress, in the media — we should all be focused on the issue of protecting the American diplomats and development experts who are working every day to advance America’s national interest and global leadership.”

Issa, in the letter, said he was issuing a subpoena that would cover “all documents and communications” for 10 current and former State Department officials.

This includes former spokeswoman Victoria Nuland, as well as nine others. Nuland is the official who, in the emails released earlier this month, could be seen pressing other agencies to remove references to prior attacks and security warnings in Benghazi — expressing concern that the warnings could be used by lawmakers to criticize the State Department.

She also questioned references to Islamic extremists.

Issa wrote that her comments suggest “that she did not raise these concerns in a vacuum,” noting specifically that Nuland said some of the changes did not “resolve all my issues or those of my building leadership.”

Issa wrote: “The documents the enclosed subpoena covers will help the Committee understand why, although on the day after the attacks senior State Department leadership believed that Islamic extremists were involved, there were reservations about publicly acknowledging any such involvement just three days later. This issue is at the heart of the Committee’s ongoing investigation.”

The committee confirmed to Fox News that the subpoena has been served.

Issa gave the department until June 7 to comply. The subpoena would cover communications under the leadership of former Secretary of State Hillary Clinton.

The intelligence community’s final talking points compiled for members of Congress suggested the Sept. 11 attack that killed U.S. Ambassador Chris Stevens and three other Americans stemmed from protests over an anti-Islamic video rather than an assault by extremists. Five days after the attack, U.N. Ambassador Susan Rice relied on the talking points in a series of interviews on the Sunday talk shows.

Republicans have accused the Obama administration of trying to mislead the American people about an act of terrorism in the heat of the presidential campaign. The White House says Rice reflected the best information available while facts were still being gathered.

After several revisions, the gist of the talking points read: “The currently available information suggests that the demonstrations in Benghazi were spontaneously inspired by the protests at the U.S. Embassy in Cairo and evolved into a direct assault against the U.S. diplomatic post in Benghazi and subsequently its annex. There are indications that extremists participated in the violent demonstrations.”

Issa said the emails and documents failed to answer the question of who else at the department other than Nuland had concerns about the early versions of the talking points. The chairman is seeking all documents and communications related to the talking points from former officials such as Nuland; Cheryl Mills, counselor and chief of staff to Clinton; and Philippe Reines, a deputy assistant secretary to Clinton; as well as Deputy Secretary of State William Burns.

British police have made two further arrests and searched multiple properties as they widened their investigation into Wednesday’s fatal hacking to death of a British soldier in broad daylight on a busy London street by two Muslim terrorists.

Read yesterday’s story of the brutal attack

The two arrests, of a man and a woman — both 29 — on suspicion of conspiracy to murder, raises the possibility that the gruesome attack was not a so-called “lone wolf” killing as once thought.  Earlier it had been reported that the attackers were known to both UK authorities and a radical jihadist group well before the shocking attack that has stunned the United Kingdom and risked inflaming tensions between communities.

The two men, who were captured on cellphone video covered in blood and spouting jihadist rhetoric moments after the attack, have not yet been named, although Scotland Yard confirmed that they remained hospitalized in stable condition after being shot by armed police at the scene. But the killers, who wielded a machete and a cleaver and were dubbed “sickening individuals” by an incensed Prime Minister David Cameron, were already on the radar of security services, according to the BBC.

And Anjem Choudary, the leader of radical Islamist organization al-Muhajiroun — a group banned under anti-terrorism laws in the UK — has told Reuters that he knows one of the reported suspects. Michael Adebolajo, named by the BBC as one of the attackers, attended a number of the organization’s demonstrations, lectures and activities according to Choudary, although he claimed not to have seen him for about two years.

Reuters reported that the two men were British citizens of Nigerian descent. Police in Lincolnshire, in eastern England, said a property was being searched in connection to the attack, and that a search warrant had been obtained but would not provide details about the search.

The Ministry of Defense has named the slain soldier as 25-year-old Drummer Lee Rigby, of 2nd Battalion The Royal Regiment of Fusiliers.

In a statement made outside his Downing Street office after having chaired a meeting of the British government’s COBRA (Cabinet Office Briefing Room A) emergency committee, British Prime Minister David Cameron refused to comment about whether security forces had prior knowledge of the suspects. However, he firmly condemned the attack in Churchillian terms, stating: “We will never give in to terror, or terrorism, in any of its forms.”

Additionally, the Conservative Prime Minister emphasized that “there is nothing in Islam that justifies this truly dreadful act,” and that the fault lay solely with the attackers. He also noted that more Muslim lives have been lost in terrorist acts than any other religion.

President Obama, in a statement Thursday afternoon, condemned the attack in strong terms, and reaffirmed the relationship between the US and the UK, stating: “The United States stands resolute with the United Kingdom, our ally and friend, against violent extremism and terror.”

Prime Minister Cameron also praised the bravery of Ingrid Loyau-Kennett, a cub scout leader and mother of two, who got off a bus and tried to reason with the attackers after she tried to help the victim lying on the street.

The 48-year-old tried to keep talking to the two attackers before police arrived at the scene near the Royal Artillery Barracks in the neighborhood of Woolwich.

In an interview with The Daily Telegraph, Loyau-Kennett said that when one of the attackers told her that they wanted to start a war in London, she responded: “It is only you versus many people. You are going to lose.”

Saying she wanted to stop one of the suspects from attacking anyone else, she asked him if he “did it” and what he wanted.

Loyau-Kennett said she saw a crashed car and the victim lying on the street and tried to help him since she had been trained in first aid. She had determined the man was dead by the time the attackers confronted her.

She said “a black guy with a black hat and a revolver in one hand and a cleaver in the other came over” and excitedly warned her to stay away from the body.

“I asked him why he had done what he had done,” The Guardian quoted her as saying. “He said he had killed the man because he [the victim] was a British soldier who killed Muslim women and children in Iraq and Afghanistan. He was furious about the British Army being over there.”

She told The Daily Telegraph that the suspected terrorist was “in full control of his decisions” and did not appear to be under the influence of drugs or alcohol.

When the man told him he was going to kill police when they arrived, she asked him if that was reasonable and tried to keep him engaged.

Then she spoke to the other attacker, who she described as quiet and shy.

“I asked him if he wanted to give me what he was holding in his hand, which was a knife, but I didn’t want to say that,” she said. “He didn’t agree and I asked him: `Do you want to carry on?’ He said: `No, no, no.’ I didn’t want to upset him,” she is quoted as saying in The Guardian.

Loyau-Kennett said she was not scared and that the armed men did not seem to be drunk or on drugs. She said she was trying to keep them occupied so they didn’t get more agitated.

She re-boarded her bus shortly before police arrived, watching from the vehicle as police shot and wounded the two unidentified suspects, who are both receiving treatment in the hospital.

“The officers shot them in the legs, I think” she told The Guardian.

The British government’s COBRA emergency committee met Thursday after Prime Minister David Cameron said there were “strong indications” it was an act of terrorism, and two other officials said there were signs the attack was motivated by radical Islam.

One of the attackers went on video to explain the crime — shouting political statements, gesturing with bloodied hands and waving a meat cleaver.

Images from the scene showed a blue car that appeared to have been used in the attack, its hood crushed and rammed into a signpost on a sidewalk that was smeared with blood. A number of weapons — including butchers’ knives, a machete and a meat cleaver — were strewn on the street.

Footage — obtained by ITV news and The Sun newspaper — showed a man in a dark jacket and knit cap walking toward a camera, clutching a meat cleaver and a knife. Speaking in English with a British accent, he apologized that female passers-by “have had to witness this” barbarity, saying that “in our land our women have to see the same.”

He gave no indication what that land was as he urged people to tell the government to “bring our troops back.” British troops are deployed in Afghanistan and recently supported the French-led intervention in Mali.

“We swear by almighty Allah we will never stop fighting you,” the man declared. “We must fight them as they fight us.” The camera then panned away to show a body lying on the ground.

Scotland Yard confirmed that counterterrorism officers were leading an investigation into the attack. Commissioner Sir Bernard Hogan-Howe said the two men had been arrested and urged Londoners to remain calm. Both men were hospitalized, one in serious condition.

Late Wednesday, riot police fanned out in Woolwich as about 50 men waving the flag of the far-right English Defense League gathered, singing nationalistic songs and shouting obscenities about the Quran.

Meanwhile, Muslim groups quickly condemned the attack, calling for the police to calm tensions. The Muslim Council of Britain called it a “barbaric act that has no basis in Islam,” adding that “no cause justifies this murder.”

Britain has been at the heart of several terror attacks or plots in recent years, the most deadly being the 2005 rush-hour suicide bombings when 52 commuters were killed. More recently, Parviz Khan was convicted in 2008 of plotting to kidnap and behead a British Muslim soldier in Birmingham.

Some extremists have lashed out at Britain’s involvement in Afghanistan and Iraq. Recently, groups have also criticized Britain’s assistance in the French-led mission to Mali to root out Islamic extremists in the north.

DEVELOPING: A man who was fatally shot by an FBI agent in Florida knew one of the suspects in the Boston Marathon bombings, a friend of the victim said Wednesday.

FOX 35 News OrlandoFBI Agent Dave Couvertier said in a statement that an unidentified agent encountered Ibragim Todashev, of Orlando, while conducting official duties.

“The agent, along with other law enforcement personnel, were interviewing an individual in connection with the Boston Marathon bombing investigation when a violent confrontation was initiated by the subject,” the statement read. “During the confrontation, the individual was killed and the agent sustained non-life threatening injuries. As this incident is under review, we have no further details at this time.”

Khusen Taramov, who was at the scene and identified himself as the victim’s friend, said Todashev, 27, knew Tamerlan Tsarnaev, the 26-year-old former amateur boxer suspected in the April 15 bombings that killed three and injured more than 260, MyFoxOrlando.com reports.

The early Wednesday shooting occurred at an apartment complex near Universal Studios in Orlando, the Associated Press reports.

Taramov said he and Todashev had no connection with the Boston Marathon bombings, but the FBI had been questioning them since the attacks.

“He used to talk on the phone with him [Tsarnaev],” Taramov said of his friend. “They talked last time a month ago. After the bombing, I couldn’t believe it. The FBI kept asking, ‘What’s the connection?’ But there is no connection … no connection.”

An FBI agent was interviewing Todashev regarding his connections to Tsarnaev and other extremists. He was originally cooperative, but was shot after attacking the agent, NBC News reports.

Taramov said Todashev had planned to soon return to Chechnya, but recently canceled his plane tickets instead.

“Me and him and my friends, we knew this was going to happen. That’s why he wanted to leave the country,” Taramov said. “But he canceled the tickets. The FBI’s been pushing him, ‘Don’t leave, don’t leave.’ So he decided to stay.”

Taramov said he was questioned by the FBI earlier Tuesday but was allowed to leave, MyFoxOrlando.com reports. When he came back, he found out that Todashev had been shot dead, he said.

“The FBI knows what happened,” Taramov said.

Messages seeking additional comment from FBI officials were not returned. Police officials in Boston told FoxNews.com they had no information regarding the shooting.

An FBI post-shooting review team has been dispatched from Washington, D.C., and expected to arrive in Orlando within 24 hours, Couvertier said in a statement.

Todashev was arrested on May 4 by the Orange County Sheriff’s Office, according to court records. He was charged with aggravated battery causing great bodily harm. Additional details were not immediately available.
