Egypt ? Al-Qaida’s No. 2 leader lashed out at President-elect Barack Obama in a new audio message Tuesday, accusing him of not doing anything to stop Israel’s offensive in the Gaza Strip, according to an intelligence monitoring center.

The recording purportedly by Ayman al-Zawahiri was al-Qaida’s first comments on the Gaza crisis since Israel launched its offensive against the Islamic militants of Hamas on Dec. 27.

In the comments, which were posted on a militant Web site and obtained by the SITE Monitoring Service, al-Zawahiri described Israel’s actions in Gaza as a “crusade against Islam and Muslims” and called it “Obama’s gift to Israel” before he takes office later this month.

“This is Obama whom the American machine of lies tried to portray as the rescuer who will change the policy of America,” al-Zawahiri said, according to SITE. “He kills your brothers and sisters in Gaza mercilessly and without affection.”
