A drone aircraft fired into a group of people preparing to attack Yemeni troops Thursday, killing a man identified as a leader of the local branch of al-Qaida and at least eight other potential attackers, according to Yemeni and security officials, who said the drone was U.S.-operated.

One of the dead was identified as Nader Al Shaddadi, one of the top leaders of al-Qaida in the region.
