Operation Mountain Storm is on along the Afghan-Pakistani frontier. US troops killed three and seized thirteen as they raided a cave militant camp in the Zabul province, Afghan southeast, a US military command spokesman said to a news conference in Kabul on Monday.
The US-led anti-Taliban coalition launched the operation a week ago to kill Taliban fighters and their allies of the Al-Qaeda international terrorist network. Twelve militants died at their bases in a US air raid of March 11.
Pashtoon militia in Pakistan blocked mountain passes along the Afghan frontier lest Taliban survivors cross it for shelter.
Reconnaissance planes are hunting information about Osama bin Laden, Al-Qaeda chief, and his men, said a source in Pentagon.
