Islamabad: A feared Taliban commander known for beheading opponents died in custody from wounds sustained during a fierce firefight with Pakistani security forces last week, the military said.

Sher Muhammad Qasab died Sunday after being critically wounded in the gunbattle in Swat Valley, the army's media center said in a statement. Qasab's three sons were killed when he was captured.

Qasab is an Urdu-language word meaning "butcher." He was given the title because of his ruthlessness toward enemies.
The arrest of Qasab - who had a $121,000 bounty on his head - was the third from the army's list of 10 most-wanted Swat militants. Qasab allegedly decapitated many Pakistani troops in Swat when the Taliban was in control.

The Pakistan Taliban has been on the run since being cleared from the scenic valley, once a tourist hotspot, and surrounding areas in July after the military launched a major offensive to retake the region in April.

The military announced Sunday that security forces killed eight militants in search operations throughout Swat since Saturday. Twenty-three insurgents were also apprehended and another 22 surrendered, it said in a statement.

One of the militants killed was a Taliban commander identified as Chamtu Khan, it said.

A Pakistani patrol also killed 10 Taliban attempting to infiltrate Swat Valley's main city of Mingora on Thursday.

The army offensive against Taliban fighters in Swat has killed more than 1,800 alleged militants, according to the military. It says 330 Pakistani troops also died in operations in the valley.
