KABUL: Afghan Vice President Marshal Mohammad Qasim Fahim, formerly one of the country’s much-feared warlords, has died of natural causes, officials said on Sunday, adding that three days of national mourning would be held. “With deep sadness, the 1st vice president, Marshal M.Q. Fahim has passed away. May his soul rest in peace,” presidential spokesman Aimal Faizi said on his Twitter account. Aged 56, Fahim was accused of being a ruthless strongman who maintained his own militia forces, but he also received American support as Afghanistan sought stability after the fall of the Taliban regime in 2001.
