U.S. warplanes launched air strikes against a suspected IS training camp in western Libya on Friday, killing more than 40 people, likely including a militant connected to two deadly attacks last year in neighbouring Tunisia, Reuters reported. It was the second U.S. air strike in three months against IS in Libya, where the hardline militants have exploited years of chaos following Muammar Gaddafi's 2011 overthrow to build up a presence on the southern shores of the Mediterranean Sea. The Pentagon said it had targeted a training camp. The facility in the city of Sabratha was linked to Noureddine Chouchane, a Tunisian blamed by his native country for attacks last year on a Tunis museum and the Sousse beach resort, which killed dozens of tourists.
