Sirens were heard at the US Embassy in Iraq Thursday night, according to reports on social media.
Reports of a bomb, shared at about 02:00 Israel time in The Jerusalem Post's sister publication Maariv, could not be confirmed as of later that night and appear to have been unsubstantiated.
The reports came after the US and Britain struck dozens of targets across Yemen, according to some reports, ranging from training bases to drone facilities.
Iranian-backed groups had warned they would respond to attacks on Houthis
It was believed to be the first time the United States had struck the Houthis since 2016, following months of attacks by the Iranian-backed rebel group against ships in the Red Sea that the group considered linked to Israel.
Reliable information on the events in Iraq was sparse, but the preliminary reports came after a previous warning by Iranian-backed militia groups in Iraq that they would attack an American base with "everything in [their] power" should the US hit Houthi targets.
