"Operations continue south of Gardez in Afghanistan. Firefights have been intense, at times in heavy combat actions. The exact size of the enemy forces occupying a series of cave complexes is not known. To date more than 80 pieces of ordnance have been dropped from aircraft in support of Afghan, US and coalition forces. Afghan, US and coalition forces are involved in eliminating al-Qaida and non-Afghan Taliban forces in the area. There has been one US Service member killed and three Afghan forces members killed. An unspecified number of US and Afghan forces have been injured."
In the biggest known U.S.-led ground operation of the war, U.S. and Afghan troops backed by U.S. jets have been attacking Taliban and al-Qaida forces regrouping in eastern Afghanistan.
U.S. bombers blasted the cavernous mountains south of Gardez for a third day on Sunday.
The coalition forces are pressing a new offensive against al-Qaida and Taliban fighters believed to be regrouping there. The bombardment was part of the largest known joint ground offensive of the war.
Speaking at southern Afghanistan's American-held Kandahar airport, the U.S. Army's 101st Airborne division spokesman, Major A.C. Roper, said the operation was "ongoing". He said one US soldier and three Afghan government soldiers had been killed with an unknown number of US and Afghan government soldiers injured.
Afghanistan's interim Interior Minister Younis Qanouni called it an operation to "to clean out" pockets of al-Qaida and Taliban fighters.
Meanwhile some of the Afghan government fighters injured in the operation were recovering on Sunday at Gardez hospital.
