The were no human or material casualties by the attack, the statement said.
A security source in Mosul told Xinhua that Katyusha rockets landed at the perimeter of al-Qayyara air base without causing casualties.
The attack came a week after thousands of demonstrators took to the streets in Baghdad upon the request of the Iraqi prominent Shiite leader Moqtada al-Sadr, in which he called for a scheduled withdrawal of U.S. troops from Iraq through peaceful means.
The Iraqi parliament passed a resolution requiring the government to end the presence of foreign forces in Iraq on Jan. 5, two days after a U.S. drone strike killed Qassem 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.
Over 5,000 U.S. troops have been deployed in Iraq to support the Iraqi forces in the battles against Islamic State militants, mainly providing training and advising to the Iraqi forces.
