Dozens of militants stormed through a town in eastern Tunisia early Monday morning, attacking police and military posts and starting a firefight with security forces that left at least 53 people dead.

U.S. warplanes struck an Islamic State camp in Libya early Friday, targeting a senior Tunisian operative linked to two major terrorist attacks in Tunisia last year.

The killer pursued sunbathers from the beach to the pool and eventually to the administration offices of the Imperial Marhaba Hotel, slaying 39 people and wounding 38 others.
