(CNN) - Insurgents attacked a U.S.-NATO base in southern Afghanistan on Saturday night, firing rockets and attempting to breach the base perimeter before security forces repelled them, the military said.
Five rockets were fired at Kandahar Air Field, according to the International Security Assistance Force in Afghanistan. Several insurgents also attempted to enter the base, but were not able to gain entry, ISAF said in a news release.
No fatalities were reported, but ISAF said some civilian workers and base personnel were injured. ISAF did not elaborate on the nature of the injuries. Base personnel were being told "to remain in safe locations as a precaution."
The attack comes three days after nearly a dozen insurgents and a U.S. contractor were killed when a group launched an early morning attack on Bagram Air Base just north of Kabul.
