On 29 July 2015, the Afghan government and state intelligence sources said that Omar had died in April 2013 two years previously in Karachi, Pakistan of tuberculosis. Some Taliban sources denied that he had died; other sources considered the report to be speculative, designed to destabilise peace negotiations in Pakistan between the Afghan government and the Taliban. A Taliban spokesman said that they would issue a statement. Abdul Hassib Seddiqi, the spokesman for Afghanistan's National Directorate of Security, claimed: "We confirm officially that he is dead".
