The U.S. military has carried out a strike in Baghdad against an Iraqi militia leader it blames for attacks against U.S. forces in the country, killing him and another person, a U.S. official told Reuters on Thursday.

The U.S. official, who spoke on condition of anonymity, said the strike hit a vehicle in Baghdad. It targeted a leader of Harakat al Nujaba, the official said, without naming the person.

Earlier on Thursday, Iraq condemned the U.S. drone attack as a "blatant assault and blatant violation of Iraq's sovereignty and security," saying four people were killed. 

Iraq said among the deceased was Talib al-Saiedi, leader of the 12th brigade and a member of the Harakat al Nujaba movement, a Shiite militia affiliated with the Hashd Shaabi forces, also known as the Popular Mobilization Forces.
