BBC: An audio message attributed to al-Qaeda's deputy leader, Ayman Zawahiri, has called for attacks on American and Israeli interests.
The voice, not confirmed as Zawahiri's, urged retaliation for Israeli raids on the Gaza Strip.
The speaker said Muslims should support Palestinians by focusing on armed struggle, not just demonstrating.
The message was posted on an Islamist website and follows two audio speeches purportedly from Osama Bin Laden.
