When will it end? At least 40 people were killed on Friday after suicide bombers struck two separate mosques in Afghanistan, officials say. One attack left at least 30 dead at a Shiite mosque in Kabul. While nobody has claimed responsibility, ISIS has targeted Shiites in the violence-ridden country, where at least 84 followers have been killed this year. The second attack, which killed 10, occurred at a Sunni mosque in the western Ghor province. Meanwhile, U.S.-led forces in Syria declared the former ISIS capital of Raqqa officially liberated.
