Video smuggled out of Iraq by an Iraqi journalist and broadcast by ABC News on Thursday appears to show members of an Iraqi special forces unit — one that has been praised by the United States — torturing and executing civilians in Mosul during a campaign against the Islamic State last year.

On Friday, a spokesman for the U.S. military coalition in Iraq and Syria said that it was aware of the journalist’s claims and had raised them with the Iraqi government.

“We take all allegations of human rights abuses very seriously and we immediately, as we did with this particular case, flag that and present it and give it to the government of Iraq for their action,” the spokesman, Col. Ryan S. Dillon, said at a news conference in London on Friday.

The disturbing footage appears to show uniformed Iraqi soldiers beating Iraqi civilians and hanging one man from the ceiling by his wrists while demanding they confess to working with the Islamic State. Iraqi officials have called for an investigation into the violence.
