(AP Photo/SITE Intelligence Group, File) (Newser) – Yemeni officials say an airstrike has killed al-Qaeda in the Arabian Peninsula's No. 2 leader, along with five others traveling with him in a car. Defense Ministry officials say today's attack killed the deputy, Saudi national Saeed al-Shihri, as he left a house in the southern Hadramawt province. They say the missile was believed to have been fired by a US operated drone. The US doesn't usually comment on such attacks, but has used drones in the past to go after al-Qaeda members in Yemen. Al-Qaeda's Yemen branch is seen as the world's most active, planning and carrying out attacks against targets in and outside US territory.
