Libya convenes militias to take action against US ambassador's killers "We have a better idea who was responsible, and we are now waiting for a government plan," said Mohammed al-Gharabi, a leader with the Union of Revolutionary Committees which run security in Benghazi. He said he was flying to Tripoli this morning for the meeting with the government, along with Fawzi Bukatif, the former deputy defence minister who is senior commander of the Union. General Yousef Mangoush, the nominal head of the army in Benghazi, is also thought to be in Tripoli. There has been no direct claim of responsibility for the killing from inside or outside Libya, and US officials are still saying that it was the result of a protest that either got out of hand or was hijacked by extremists. But there is increasing evidence that it was a co-ordinated assault that had been planned in advance. On Monday, a security guard wounded in the attack told The Daily Telegraph that there had been no demonstration before hand but the attack had come out of the blue. He said there was a single warning shot, and then hand grenades were lobbed over the wall, accompanied by heavy shooting from automatic rifles and rocket-propelled grenades. He said more than 30 men managed to charge the gates. "They were shouting, 'Kill the bastards'," he said, adding there were no religious or protest slogans. He said they saw him and identified him as a Libyan defender of the consulate. They said, 'Kill the dog!' Among those that now appear not to be true is the claim that the ambassador, Christopher Stevens, was dead when he was found in a secure room. Video posted online yesterday appeared to show a group of civilians finding him and declaring he was still alive. "Allahu akbar," they shout as one man declares he is breathing. One member of the brigade sent to help clear the consulate said he had helped carry Mr Stevens, still alive, to the car that took him to hospital. However, the evidence of the security guard, who is still being treated for his injuries and is not being named for his own protection, is more significant to the investigations being conducted in both the United States and Libya into the killing. It's approximately a reaction to this video, and it's a hateful video that had nothing to do with the United States," Miss Rice said. Officials told The Wall Street Journal they had records of telephone conversations on Tuesday between Al-Qaeda and members of a Benghazi-based Islamist militia, Ansar al-Sharia. ends Attachment has been stripped.
