ISLAMABAD, Pakistan (CNN) -- Two key figures connected to the Taliban in Pakistan's Swat Valley were killed Saturday during a military convoy ambush, officials said.
Pakistan security forces were transporting Amir Izat Khan and Maulana Muhammad Alam from Malakand to Peshawar when their convoy was attacked by militants, the military said.
Both prisoners were killed in the battle. It was unclear whether they were killed by the Taliban or security forces. The men were senior members of an organization run by Sufi Muhammad.
Muhammad represented the Swat Valley Taliban in the recent failed peace efforts between the Pakistani Taliban and the local government. He is also the father-in-law of Maulana Fazlullah, leader of the Pakistan Taliban in the Swat Valley.
An officer was also killed in the battle and five others were injured, the Pakistani military said.
The killings come as Pakistan has waged a month-long military offensive against the Taliban for control of the Swat Valley.
An estimated 2 million Pakistanis have been displaced by the fighting in the past month, according to the United Nations.
