US orders non-essential staff from Tunisia and Sudan In the worst violence sparked by the film, the US ambassador to Libya, Chris Stevens, and three other Americans died when suspected Islamic militants fired rocket-propelled grenades at the US consulate in the eastern city of Benghazi. In cities across the Muslim world protesters have since vented their fury at the "Innocence of Muslims" - an amateur film produced in the United States - by targeting symbols of US influence ranging from embassies and schools to fast food chains. Although the US government itself has condemned the film, protests erupted again on Sunday, with hundreds of students pouring into the streets of Kabul shouting anti-American slogans, as the Bangladesh government condemned the film as "reprehensible." With Muslim anger boiling, al-Qaeda in the Arabian Peninsula (AQAP) issued a call for more violence against US diplomatic missions in the Middle East and Africa, and urged attacks on US interests in the West, the SITE Intelligence Group said. AQAP, al-Qaeda's Yemeni offshoot, did not claim direct responsibility for the deadly attack in Benghazi. But it said the killing of al-Qaeda deputy leader Sheikh Abu Yahya al-Libi in a June drone strike in Pakistan "increased the enthusiasm and determination of the sons of [Libyan independence hero] Omar al-Mukhtar to take revenge upon those who attack our Prophet," according to SITE. In Afghanistan, heavily armed Taliban fighters on Friday stormed a strongly fortified air base in Helmand province where Britain's Prince Harry is deployed, killing two US Marines in an assault the militia said was to avenge the anti-Islam film. A NATO spokesman on Sunday revealed that six US fighter jets and three refuelling stations were destroyed and six aircraft hangars damaged in the attack. US Secretary of State Hillary Clinton undertook a round of telephone diplomacy Saturday, calling her counterparts in Egypt, Saudi Arabia, Turkey, Britain and France, as well as the prime minister of Libya and the Somali president, in a bid to rally support, State Department spokeswoman Victoria Nuland said.
