President Barack Obama has paid tribute to the American ambassador who died in the violence which led to the Embassy building in Libya being torched. He said 'no acts of terror' will shake America's resolve. Chris Stevens was one of four diplomatic staff killed as protestors fired shots into the building and looted its contents. A graphic picture has appeared online showing embassy staff dragging Mr Stevens away from the scene of the attack to the hospital. Apparently doctors tried for 90 minutes to revive him.

Chris Stevens had been the US Ambassador to Libya since May last year. The 52-year-old was interviewed on the country's Al-Hurra last summer and optimistic about the country's future when he arrived. The angry protests that resulting in his death and 3 more US diplomatic staff were over a YouTube film, produced by an Israeli-American, which ridicules the Prophet Mohammed. Muslims view that any depiction of Him as an insult to their faith. Libya's Deputy Interior Minister has blamed America for not taking extra security measures when protests erupted.

President Obama, on the other hand, was unequivocal in his condemnation of the 'outrageous and shocking attack'.

Libya's interim president called the attacks cowardly. And the British Foreign Minister William Hague condemned it as 'brutal and senseless'.

Meanwhile the man behind the film which lead to the violence, Sam Bacile is in hiding.
