BAGHDAD: At least two rockets hit the heavily fortified Green Zone in central Baghdad, an Iraqi Interior Ministry official said.
The incident happened at around 12 a.m. on Sunday when unknown militants fired the rockets at the zone, which houses a number of the most Iraqi government offices and therefore the US embassy, the official told Xinhua press agency.
Sirens were heard in the zone because the rockets landed on a vacant area and caused no casualty, the official added.
The Green Zone, which is heavily fortified, has been frequently targeted by insurgents' mortar and rocket attacks.
The roughly 10-square-km zone is found on the West Bank of the Tigris, which bisects the Iraqi capital.
