The Taliban leader said he had ordered the formation of a "Political Office" that was "entrusted with the responsibility of monitoring and conducting all political activities."
"The objective behind our political endeavors as well as contacts and interactions with countries of the world and our own Afghans is to bring an end to the occupation and to establish an independent Islamic system in our country," he said, after explaining at length why negotiating with "infidels" is permitted by the Quran and actions of the Prophet Mohammed.

for the first time in an attempt to work toward a peace process.

also sent an apparent warning to ISIS, the Sunni extremist group that has seized a swath of territory across Syria

The U.S. combat mission in Afghanistan ended last year, leaving the Afghan military to lead the fight against the Taliban. The thousands of NATO troops that remain in Afghanistan are there in a training and support role.
