The U.S. military in Afghanistan says a mortar attack at a base in eastern Paktika province has killed two U.S. military personnel, with eight others wounded.

A military statement says the mortar landed in the base near Shkin, near the Pakistani border, as the victims were preparing to unload supplies from a Chinook helicopter.

Also Wednesday, U.S.-led coalition forces arrested five suspected Taleban insurgents in connection with an attack on an oil tanker that killed two Pakistanis.

Police in the Afghan border town of Spin Boldak said the five suspects were apprehended one day after the two Pakistani nationals were killed in the same area.

The Taleban and their militant allies have stepped up attacks in recent months, often hitting soft targets associated with coalition forces and the Afghan government of President Hamid Karzai.
