Al-Qaeda leader killed in drone attack

A military airstrike in northwest Syria has killed the leader of an al-Qaeda cell that American officials say has been plotting attacks against the United States and Europe, announced the Pentagon on Sunday.

The leader, Sanafi al-Nasr, a Saudi citizen, was the highest-ranking leader of a network of about two dozen veteran Qaeda operatives called the Khorasan Group, and the fifth senior member of the group to be killed in the past four months. His death was announced in a Pentagon statement describing Thursday’s operation, which American officials said was a drone strike.
