DUBAI: New Al-Qaeda leader Ayman al-Zawahri voiced support in an Internet video for popular revolts shaking the Middle East, saying Arabs no longer feared the United States 10 years after the country was targeted by the militant network.

“Ten years have passed since the blessed attacks on New York and Washington and Pennsylvania, that mighty event which shook and continues to shake the pillars of the global crusade,” Zawahri said in the video posted on Islamist websites Tuesday to mark the anniversary of the Sept. 11, 2001 attacks.

Zawahri, an Egyptian who took up the reins of Al-Qaeda after the killing of Osama bin Laden in May, hailed popular uprisings that have toppled leaders in Egypt, Tunisia and Libya this year, and urged other Muslims to overthrow their rulers too.

“The Arab people have been freed from the chains of fear and terror, so who is the winner and who is the loser?” he said.

In the hour-long recording, titled “The Dawn of Imminent Victory,” Zawahri expressed hope that the fall of Arab rulers he said were in thrall to the West would usher in an era of true Islam and Shariah-based governance.

“The blessed rebellious Arab earthquake has turned America’s calculations head over heels,” he said, adding the United States had lost key regional allies in the upheaval.

“We ask God that the spring of strength and liberation be the bitter winter of America and a dark tunnel from which it will not emerge except in defeat,” Zawahri said in the audio message played over a still photograph of him brandishing a gun.

Zawahri called on Syrians to persevere in their struggle against the “corrupt and criminal” rule of President Bashar Assad and welcomed the overthrow of Libyan leader Moammar Gadhafi, though he criticized NATO’s involvement.
