American warplanes struck multiple targets in Libya overnight, hitting what was apparently an Islamic State training camp, the AP reports. The big strike took place on a camp near the city of Sabratha, where the mayor says about 40 were killed, reports Reuters. One US official tells the New York Times that the target was a senior militant identified as Noureddine Chouchane, who's believed to be behind two major attacks in Tunisia last year, one at a beach and the other at a museum. The camp is near the Tunsian border, and it's not yet clear whether Chouchane was killed in the strikes.
