"Since we have conducted several strikes near Raqa we will provide this information to our civilian casualty team for further investigation," the spokesman said, following reports that a coalition strike killed 33 civilians in the northern Syrian province of the same name.
The civilians were killed in the reported air strike early yesterday, according to the Syrian Observatory for Human Rights.
The monitor said today that the strike hit a school being used as a temporary shelter for displaced families, about 30 kilometers (20 miles) west of IS-held Raqa city.
"They're still pulling bodies out of the rubble until now. Only two people were pulled out alive," Abdel Rahman told AFP.
The air strike came ahead of a today meeting of top officials in Washington focused on defeating the Islamic State group.
Years of diplomatic efforts have failed to end Syria's raging six-year conflict, which began with protests against President Bashar al-Assad.
