Ghani: IS terror threat squeezing Afghanistan

Afghan President Ashraf Ghani warned Wednesday that Islamist extremists will soon "come knocking on our door," and stressed to US lawmakers that the region must unite in a battle against them. "If one story of our future history is bright, there is another, darker cloud that is making its way towards our country," Ghani told a joint meeting of Congress during his first trip to Washington as leader of Afghanistan.
