Taliban Foreign Minister Amir Khan Muttaqi made the request in a letter to U.N. Secretary-General Antonio Guterres on Monday. Muttaqi asked to speak during the annual high-level meeting of the General Assembly, which finishes on Monday.
Guterres' spokesperson, Farhan Haq, confirmed Muttaqi's letter. The move sets up a showdown with Ghulam Isaczai, the U.N. ambassador in New York representing Afghanistan's government ousted last month by the Taliban.
Haq said the rival requests for Afghanistan's U.N. seat had been sent to a nine-member credentials committee, whose members include the United States, China and Russia. The committee is unlikely to meet on the issue before Monday, so it is doubtful that the Taliban foreign minister will address the world body.
