NATO says insurgents tried to storm a combat outpost in eastern Afghanistan, setting off a battle that killed 30 attackers and wounded five coalition soldiers.

Assailants struck the military post from all sides using small arms, rocket-propelled grenades and mortars.

The outpost is in Paktika province's Bermal district. Nearly all NATO forces in the province are from the U.S. military.

NATO said coalition forces called in close air-support and airstrikes to help repel the 1:30 a.m. attack.

In a statement, the military said five coalition service members were wounded during the attack but continued fighting.

Saturday's attack took place in an area about 125 miles (200 kilometers) south of Kabul.
