At least three rockets have been fired at a U-S military base in eastern Afghanistan.
The privately-run Afghan Islamic Press news agency says the rockets landed at the air base in the city of Khost late Monday. The agency says U-S aircraft flew over the base after the attack but took no action to retaliate.
The agency says there were no casualties but did not say whether the rockets caused any damage.
Khost was formerly a stronghold of Afghanistan's ousted Taleban rulers and the al-Qaida terrorist network of Osama bin Laden. The air base has come under sporadic, but mostly ineffective attack since U-S forces arrived there late last year.
