Sirte, Libya—Libyan forces allied with the U.N.-backed government fire a rocket at Islamic State fighters on August 4. The United States launched airstrikes against ISIS targets there in early August at the request of the government, which has been trying since May to take back the city seized by militants in early 2015. The U.S. intervention marked an expansion of its fight against ISIS, which has built up a powerful network in Libya from its stronghold in the coastal city of Sirte, which was Muammar el-Qaddafi’s hometown.
