Four members of al Qaeda’s Yemen branch were killed late Friday in what local authorities said was a U.S. drone strike. One of those killed was reportedly a local commander of the terrorist group. The attack took place late Friday in Marib province as the four men traveled east from Sanaa in a vehicle. The attack marks the second drone strike in two days targeting al Qaeda in Yemen, which U.S. officials consider to be one of the most dangerous branches of the group. On Thursday, a drone strike on a vehicle in al-Bayda province reportedly killed one of the group’s regional commanders.
