KARACHI: The Tehrik-i-Taliban Pakistan (TTP) chief Hakimullah Mehsud appeared in a video obtained by DawnNews of the killing of former ISI official Sultan Amir Tarar alias Colonel Imam.

Colonel Imam had gone missing on March 25 last year along with another former ISI official, Khalid Khwaja, and a British journalist of Pakistan origin, Asad Qureshi, while they were going from Kohat to North Waziristan.

Sultan Amir Tarar was believed to have a key role in the growth of the Taliban movement in Afghanistan.

Earlier, on April 30, 2010, Khalid Khwaja was found dead near a stream in Karam Kot, about seven kilometres south of North Waziristan’s main town of Mirali. A note attached to his body said he was with the CIA and the ISI.

The disappearance of the three men had created ripples in the official circles because the purpose of their visit was not clear.
