After ouster, Islamic State fighters continue to reap rewards from a lucrative smuggling hub. It has been more than a year since Libyan forces pushed Islamic State fighters from the country's coast, where the militant group held a short-lived caliphate just a few hundred miles from Europe. But Libya remains in turmoil amid a civil war, and since its ouster from Libyan cities, ISIS has regrouped in the surrounding desert, launching more than a dozen deadly attacks so far this year. In the coastal city of Sabratha, home to spectacular Roman ruins, security forces say ISIS is working hand in hand with migrant traffickers along the coast ferrying people from sub-Saharan Africa to Europe. NewsHour Weekend Special Correspondent Christopher Livesay traveled to Sabratha to report on the second of a two-part series on ISIS in Libya.
