A NATO airbase in Afghanistan where U.S. forces are stationed came under enemy fire Saturday.
But NATO says the two rockets that struck the base on the outskirts of the eastern city of Jalalabad did no damage to equipment or buildings.
A provincial government spokesman had reported several explosions and said sporadic gunfire rang out for around a half an hour as helicopters flew overhead.
NATO says there were no fatalities and the base was later secured.
The attack came as scattered violence elsewhere in Afghanistan left 13 people dead.
