Top Iraqi politicians joined the United Nations Thursday in condemning a rocket attack north of Baghdad that killed a British soldier and two Americans and threatened a new escalation.
A volley of 18 rockets slammed into the Taji air base late Wednesday, killing a British soldier, a US soldier and an American contractor in the deadliest attack in years on US forces in Iraq.
There was no claim of responsibility but Washington has accused Iran-backed factions of Iraq's IMIS of carrying out similar attacks.
Within hours, air raids killed 26 Iran-aligned Iraqi fighters in neighbouring Syria, prompting fears that tensions between Washington and Tehran would once again flare up.
