Dushanbe, 25.05.2016 / NIAT “Khovar” /. Mullah Akhtar Mohammad Mansour has been chosen as the head of the Afghan Taliban, according to two commanders of the Islamic militant organization.

The commanders said the long-time deputy of the deceased Mullah Omar was elected at a shura or meeting of top Taliban representatives just outside the Pakistani city of Quetta where many of them are based, Reuters reports.

Siraj Haqqani, who leads the Haqqani militant faction within the Taliban, has been selected as Mansour’s deputy. Mansour is only the Taliban’s second-ever leader, with Omar having been at the helm since founding the Afghanistan-based militant organization in the 1990s.

Taliban spokesman Zabihullah Mujahid confirmed reports of Omar’s death, although he said it occurred more recently than April 2013—the date given by the Afghanistan government earlier this week.

“For some time, (Omar) has been suffering a kind of sickness and over the last two weeks it became more serious, and due to that illness he passed away,” Mujahid said. The Taliban founder has not been seen in public since 2001, leading to widespread speculation of his whereabouts and multiple reports of his death over the last decade.

Peace talks between the Taliban and the current Afghanistan government, due to be held in and mediated by neighboring Pakistan, have been postponed indefinitely in the meantime. Pakistan cited the reports of Omar’s death as the reason for delaying the talks, because of concerns that a battle for succession could further deepen discord between the Taliban’s numerous factions.
