Air strikes killed about 55 suspected al-Qaeda operatives in southern Yemen on Sunday, officials said, in what was called an "unprecedented" series of strikes.
According to the nation’s High Security Committee, the operation focused on "terrorist elements [who] were planning to target vital civilian and military installations." An unnamed high-level Yemeni official told CNN that the "massive and unprecedented" strike involved commandos who are now "going after high-level AQAP [al-Qaeda in the Arabian Peninsula] targets." He said the operation was launched in collaboration with the U.S., though wouldn't confirm the use of drones in the attack. The U.S. is known to have conducted drone strikes in Yemen.
Predawn strikes targeted a mountain ridge in the southern province of Abyan, according to the official, while Yemen's state news agency SABA said three strikes hit an al-Qaeda training camp around 450 km south of the capital Sana‘a.
AQAP is one of the terrorist group's most lethal wings.
