In a phone call with U.S. Secretary of State Mike Pompeo, Iraqi Prime Minister Adel Abdul Mahdi asked the United States to send a delegation to Iraq to set up a mechanism for U.S. troop withdrawal from the country, a statement from the prime minister‘s office said Friday.

The request followed a vote by the Iraqi parliament to expel thousands of U.S. troops, a direct consequence of a U.S. drone attack that killed senior Iranian commander Qasem Soleimani and nine companions in Baghdad a week ago.
