A drone strike Friday killed an Al-Qaeda leader in Yemen, a tribal source said, the latest in a string of attacks on what is considered the extremist group\'s most dangerous network. The source told AFP the early morning strike on a vehicle travelling in Manasseh village in the southern province of Bayda killed Qaeed al-Dhahab and two other men. Some 10 drone strikes since July 28 in eastern, southern and southeast Yemen have killed more than 40 people. They are thought to be carried by the United States, the only country in the region to have drones.
