Mustafa Abu Yazid, al Qaeda’s comander in Afghanistan, vowed to avenge the death of Abu Laith al Libi, the al Qaeda field commander killed in an airstrike in North Waziristan, Pakistan. “The men he trained … will not rest until they avenge him and realise his aspirations and hopes, God willing,” he said. Yazid released a videotape via As Sahab, al Qaeda’s media arm.
