Osama bin Laden's deputy has appeared in a new videotape threatening Britain with more terror attacks and warning the United States it could face thousands of military casualties in Iraq if it does not withdraw its troops.

Al-Qaida deputy Ayman al-Zawahiri did not directly claim al-Qaida carried out the July 7 London attacks in the video aired Thursday on the Arab satellite channel al-Jazeera. But he said further attacks would be the fault of British Prime Minister Tony Blair's policies.

Of the United States, he said losses in the September 11, 2001 attacks, and in Iraq and Afghanistan, would only be the beginning until "you withdraw from our land, stop stealing our oil and resources, and end support for corrupt rulers."

Ayman al-Zawahiri last appeared in a videotape on June 17, in which he said peaceful change was not possible.
