Radical Shia cleric Muqtada al Sadr said that US troops supporting the Iraqi military’s offensive to retake Mosul from the Islamic State should be targeted by his militias.

Sadr, who openly fought US troops several times during the US occupation, made the statement in response to a question from a follower on how they should respond to the US military’s deployment of additional troops to aid Iraqi forces in retaking Mosul.

“They are a target for us,” Sadr said on his website, according to Reuters.

US Secretary of Defense Ashton Carter announced last week that the US military would send 560 more troops to Iraq to capitalize on recent Iraqi military success in Qayarra south of Mosul.
