Clear details are yet to emerge, but the U.S. government appears to have launched a number of drone strikes against key members of al-Qaeda in the Arabian Peninsula, the Yemeni branch of the global terrorist organization, over the weekend. The attacks come after AQAP released a video in late March (screenshot below) showing its leader and al-Qaeda’s global manager, Nasir al-Wuhayshi, speaking to a large gathering of fighters in Yemen and promising that the U.S. is still the group’s top target.

Yemeni officials say that about two dozen fighters were killed in the strikes. The Long War Journal reports that the missions were intended to kill not Wuhayshi but AQAP’s top bomb-maker, who has been involved in a number of attempted attacks on the West. The bomb-maker was reportedly among one of the convoys hit by the weekend’s drone strikes, but his death hasn’t been confirmed.

UPDATE: U.S. officials tell CNN that more than 60 al-Qaeda members have been killed in Yemen over the last three days.
