Iran has blacklisted the U.S. ambassador in Yemen, the Iranian foreign ministry said on Wednesday, a day after Washington imposed terrorism-related sanctions on Tehran's envoy to the Yemeni Houthis.
Tehran's move, which allows the seizure of assets within Iran of sanctioned individuals, is symbolic and unlikely to have any impact on the U.S. ambassador.
"Highlighting his key role in Yemen's humanitarian crisis, Iran puts Christopher Henzel's name on its sanctions list," the ministry said in a statement on its website.
