Two rockets landed near the US embassy in Baghdad overnight, security sources told AFP early Tuesday (September 24th), with foreign diplomats there reporting emergency sirens repeatedly going off.

The latest attack within the walled-off Green Zone, which hosts foreign embassies and Iraqi government buildings, comes amid heightened tensions between Iran and the US.

A foreign security source inside the Green Zone said two 100mm rockets hit close to the US embassy and a third fell into the Tigris River, which the embassy overlooks.

"One hit about three meters inside a gate on the embassy compound," the source told AFP.

An Iraqi security source confirmed to AFP that two Katyusha rockets landed near the embassy shortly before midnight.

They were found to have been fired from an area in southern Baghdad where Iraqi paramilitary forces close to Iran hold sway.

The Iraqi military said two projectiles hit the edges of the Green Zone.

None of the sources mentioned any casualties and no group claimed responsibility for the attacks.

Foreign diplomatic sources within the zone said US embassy sirens wailed across the area twice, and stopped shortly before 1:00 a.m. local time on Tuesday morning.

The last rocket attack on the Green Zone took place on May 19th, just days after the US announced an "ordered departure" of all non-essential diplomatic staff in Iraq.
