The US-led coalition said on Tuesday that it would not tolerate any attacks against its personnel after rockets were fired overnight at Baghdad’s fortified Green Zone.
It added that the attacks on coalition personnel and facilities "will not be tolerated,"
U.S. and coalition-occupied facilities in the area were not hit by the rockets but the coalition would defend itself if it were targeted, it said in a statement.
There was no claim of responsibility for the rocket attack. One rocket landed in the Tigris river and another hit in the Green Zone without causing casualties or damage, Iraqi security services said.
Similar attacks in the past have sometimes been blamed by Iraqi forces on Iranian-backed militias in Baghdad.
Monday's attack comes amid heightened tensions in the region following an attack on Saudi oil installations that the U.S. has blamed on Iran.
