Afghanistan said on Wednesday that Mullah Omar, the elusive leader of the Taliban movement fighting to topple the government, died more than two years ago.

The announcement came a day or so before a second round of peace talks had been tentatively scheduled, and news of the fate of the one-eyed Omar could deepen Taliban divisions over whether to pursue negotiations with Kabul and who should replace him.

Omar had not been seen in public since fleeing when the Taliban was toppled from power by a U.S.-led coalition in 2001, and there has been speculation for years among militant circles that he was either incapacitated or had died.
