Hatim Mehsud, affiliated with the Tehrik-e-Taliban Pakistan (TTP) chief Hakimullah Mehsud, was killed during exchange of fire with the rival Waliur Rehman group, police said today.
The incident took place yesterday in Gulshan-e-Bunair area on the outskirts of Karachi, the financial hub of Pakistan.
"The fighting erupted as part of a turf war," an official said.
A contingent of security personnel, including Rangers and police, conducted a targeted operation in the area and detained around two dozen suspects following the incident.
They also recovered a huge cache of arms including a 7.5 kg bomb.
Mehsud group's chief operational commander in Karachi, Sher Khan Mehsud was also among those killed by rival groups, apparently backed by Waliur Rehman, a senior TTP commander based in South Waziristan.
