Al-Qaida's media wing has announced the terror group's No. 2, Ayman al-Zawahri, will soon issue a new message on the anniversary of the 1967 Arab-Israeli war. The announcement by al-Sahab media group was posted on an Islamic Web site that commonly carries militant messages. It says a "statement" by al-Zawahri, who is Osama bin Laden's deputy, will be entitled: "Stop the blockade of Gaza." It didn't say whether it would be in audio or video format. On June 5, 1967, Israeli warplanes destroyed 400 aircraft belonging to Egypt, Syria, Jordan and Iraq - most of them on airport tarmacs. Arabs have long called the Six Day War the "naksa" - or "setback" in Arabic _ but its impact remains a deep wound. Al-Qaida's messages typically appear within 72 hours of announcement.
