In southwestern Libya, officials say a drone strike on the remote town of Murzuq Sunday killed 42 people and injured 60 others — 30 of them critically. The U.N.-backed government in Tripoli blamed the assault on forces loyal to the Benghazi-based warlord Khalifa Haftar, who launched an offensive in April aimed at seizing the capital. Haftar is a former CIA asset whom the White House has praised for his “role in fighting terrorism and securing Libya’s oil resources.”
