Iraqi forces in co-ordination with US-backed Syrian forces have captured five senior Islamic State leaders, the US-led coalition said.
In a statement, coalition spokesman Army Colonel Ryan Dillon called the arrests a "significant blow to Daesh", using the Arabic acronym for the extremist group.
IS fighters no longer control significant pockets of territory inside Iraq, but do maintain a grip inside Syria along Iraq's border.
The US-led coalition supported Iraqi ground forces and Syrian fighters known as the Syrian Democratic Forces in the more than three-year war against IS.
US President Donald Trump tweeted about the raid, saying those arrested were the "five most wanted" IS "leaders".
