US told of Libyan attack claim

The document may fuel Republican efforts to show that the White House knew it was a terrorist attack, even as the US ambassador to the United Nations was saying – five days afterwards – that it appeared to be a protest gone wrong.

The Obama administration’s account of the Benghazi events has become a campaign issue, with presidential challenger Mitt Romney and Republican politicians accusing the White House of misleading Americans about the nature of the attack. But militant groups often surface after such attacks claiming responsibility and it is difficult to immediately verify such claims.

News organisations obtained the unclassified email and two related emails from government officials who requested anonymity because they were not authorised to speak about them publicly.

The House of Representatives and Senate committees that oversee intelligence received a raft of documents from the Office of Director of National Intelligence on Monday, two congressional aides said.

Congressional staffers combing through the documents have found a kaleidoscope of sometimes conflicting intelligence, backing up much of what intelligence officials explained over the past several weeks.

But members of both committees are still complaining that the original briefing they were given just after the Tuesday, September 11 attack differed markedly from the explanation CIA director David Petraeus gave them by the end of that week.

In that first briefing, just 12 hours after consulate was burned down, the intelligence committees received a report that it was a military-style assault, but just days later, Mr Petraeus stressed that militants had infiltrated a mob, a US official said.

US intelligence officials have said Mr Petraeus outlined that extremists were believed to be in the crowd, and carried out the attack, and also stressed the picture was still evolving.

An intelligence official said yesterday that it was “clear from the outset that a group of people gathered that evening” but that it took until the week after the attack to determine “whether extremists took over a crowd or if the guys who showed up were all militants”.

The official said the briefing included the analysis that the “attacks that appeared spontaneous” but also mentioned possible links to regional al Qaida groups.

US secretary of state Hillary Clinton said the review board she appointed to investigate the attack was “looking at everything”, rather than “cherry picking one story here or one document there”.

She added, “What I keep in mind is that four brave Americans were killed and we will find out what happened, we will take whatever measures are necessary to fix anything that needs to be fixed and we will bring those to justice who committed these murders.”

White House press secretary Jay Carney said the emails represented just one piece of information the administration was receiving at the time.

“There were emails about all sorts of information that was becoming available in the aftermath of the attack,” he said. “The whole point of an intelligence community and what they do is to assess strands of information and make judgments about what happened and who is responsible.”

Mr Carney, travelling with President Barack Obama on Air Force One, said the emails were unclassified and referred to assertions made on a social media site.

There were a series of three emails sent by State Department officials in Washington as events unfolded on September 11. Among the recipients was the White House situation room.

The first email said that the State Department’s regional security officer reported the mission in Benghazi was under attack, and that “20 armed people fired shots”. It said that ambassador Chris

Stevens, who was killed in the attack, was in Benghazi, and that he and four others were in the compound’s safe haven.

Forty-nine minutes later, an email said that the firing at the consulate “has stopped and the compound has been cleared”, while a response team was attempting to locate people.

The next message, one hour and 13 minutes after the second and some two hours after the attack began, a message reported that Ansar-al-Sharia claimed responsibility for the attack.

Nearly six hours after the initial attack, a State Department memo said the shelter location for the Americans was receiving mortar fire and “there are reports of injuries”.

Ansar al-Sharia bragged to members of al Qaida in the Islamic Maghreb that it was responsible for the attack, according to recordings of phone calls intercepted by US intelligence. But the group has publicly denied having any involvement.

Meanwhile, the Tunisian government said it had arrested Ali Harzi, a 28-year-old Tunisian linked to the US consulate attack, and an Egyptian security official said an Egyptian militant suspected of involvement had been killed in clashes in Cairo.
