Two Katyusha rockets on Wednesday landed near the U.S. embassy in the heavily fortified Green Zone in central Baghdad, an Interior Ministry official said.

The attack took place around midnight when the two rockets landed near the U.S. embassy in the Green Zone which also houses some of the main Iraqi government offices.

There were no immediate reports about casualties, the source said.

The heavily fortified Green Zone has been frequently targeted by insurgents' mortar and rocket attacks. The roughly 10-square-kilometer zone is located on the western bank of the Tigris River, which bisects the Iraqi capital.

Last week, a U.S. drone attacked a convoy at Baghdad International Airport, killing Qasem Soleimani, commander of the Quds Force of Iran's Islamic Revolution Guards Corps, and Abu Mahdi al-Muhandis, deputy chief of Iraq's paramilitary Hashd Shaabi forces.

More than 5,000 U.S. troops have been deployed in Iraq to support the Iraqi forces in the battles against ISIL militants.
