Afghan first Vice-President and powerful former warlord Marshal Mohammad Qasim Fahim died on Sunday, the presidential spokesman said.

“The first Vice-President Marshal MQ Fahim has passed away. May his soul rest in peace,” government spokesman Aimal Faizi tweeted.

Fahim was the leader of the powerful Northern Alliance resistance group, which took over Kabul from the Taliban in 2001 with the support of US troops.

Faizi also said the government has ordered a three-day period of national mourning, with the national flag at half-mast.
