The United States has asked Uzbekistan to join the coalition against the Islamic State, a U.S. official said Thursday. Daniel Rosenblum, U.S. deputy assistant secretary of state for Central Asia, told reporters the country can choose what ways they'd like to contribute to the fight against ISIS, Reuters reports. The coalition has a military component and five or six other "lines of effort," Rosenblum said. Uzbekistan is home to 31 million people, mostly Muslims.
