Al-Qaeda calls for fresh attacks, US pulls embassy staff

Al-Qaeda called for fresh attacks against US targets in the Arab world and the West, as Washington said it was pulling non-essential embassy staff out of Sudan and Tunisia.

Al-Qaeda in the Arabian Peninsula (AQAP) also called for more violence against US diplomatic missions in West Asia and Africa, and urged Muslims in the West to attack US interests, SITE Intelligence Group said.

The US State Department ordered all non-essential personnel to leave Sudan and Tunisia following embassy attacks over an anti-Islam video, warning US citizens against travel there.

Hours earlier, Sudan had refused a US request to send in special forces to protect the Khartoum embassy, after protesters attacked it on Friday.

In cities across the Muslim world protesters have vented their fury at a US-made film, targeting symbols of US influence ranging from embassies and schools to fast food chains.

As US investigators questioned the man allegedly behind the low-budget movie before releasing him, the top Sunni Muslim authority called for a worldwide ban on all forms of attacks on Islam and other religions.

Federal authorities questioned Nakoula Besseley Nakoula in Los Angeles, trying to establish whether he had broken the terms of his probation over a bank fraud conspiracy, Los Angeles County Sheriff's Department spokesman Don Walker told AFP.

In the worst violence triggered by the anti-Iswlam film , the US ambassador to Libya, Chris Stevens, and three other Americans were killed late Tuesday when suspected Islamic militants fired rocket-propelled grenades at the US consulate in Benghazi.

AQAP, al-Qaeda's Yemeni offshoot, did not claim direct responsibility for the attack in the eastern Libyan city.

But it said the killing of al-Qaeda deputy leader Sheikh Abu Yahya al-Libi in a drone strike in June "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.

"May the expulsion of embassies and consulates lead to the liberation of Arab lands from the American hegemony and arrogance," it said in another statement.

It was a duty for Muslims on Western soil to attack US interests, it added.

In Afghanistan, heavily armed Taliban 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 American-made film.
