Afghan and NATO-led troops killed 50 to 60 Taliban fighters during an attack by insurgents on a base in a volatile eastern province of Afghanistan near the border with Pakistan late Tuesday, a provincial government spokesman said Wednesday.

The NATO-led International Security Assistance Force (ISAF) confirmed there had been an attack on a base in the Barmal district of eastern Paktika province. Mukhlis Afghan, a spokesman for the Paktika governor, put the number of Taliban fighters killed at between 50 and 60.

An ISAF spokesman said a large group of insurgents attacked the ISAF base using small arms and rocket-propelled grenades. ISAF troops fought back, causing significant casualties among the insurgents.

He said two buildings used by insurgents were destroyed in the fighting, which included ISAF air strikes, but said there had been no reports of civilian casualties.
