A drone strike killed six suspected al Qaeda militants in an overnight attack in eastern Yemen, tribal sources said on Thursday.
Al Qaeda in the Arabian Peninsula has taken advantage of a conflict pitting Houthi militiamen against forces loyal to President Abd-Rabbu Mansour Hadi to grab territory and operate more openly.
The United States has kept up a drone campaign against the militants, adding to near-daily air strikes by a Saudi-led Gulf Arab coalition, which intervened in the war last March to rout the Iran-backed Houthis and restore Hadi's government.
