US Investigates Alleged IS Plot to Kill American Peace Envoy to Afghanistan Jeff Seldin WASHINGTON/ISLAMABAD - U.S. officials say they are seriously investigating Taliban claims that Islamic State in Afghanistan was plotting to assassinate Zalmay Khalilzad, the American peace envoy for the country. The Taliban have recently shared with journalists a video of two blindfolded men in their custody, saying they were recruited by Islamic State for the would-be suicide mission aimed at killing Khalilzad. "The U.S. government takes any potential threat against U.S. personnel seriously," a State Department spokesperson told VOA when contacted for a reaction. "U.S. officials are investigating the video, in addition to Afghan government authorities," the spokesperson added. .
