US’s outgoing special representative for Afghan peace Zalmay Khalilzad said that war in Afghanistan ended but warned that this is not the final chapter as the people of Afghanistan will confront economic and security challenges.

Zalmay Khalilzad in a series of Twitter posts officially confirmed his resignation from the post of special representative of the United States to Afghanistan’s reconciliation and welcomed his deputy Thomas West to the post.

US secretary of State Antonio Blinken had praised him and expressed gratitude for all his efforts as their special envoy to his native country.

Zalmay Khalilzad said that it was an honor for him to serve the people of America and added to remain committed to peace and stability in Afghanistan.

“I thank all my colleagues at the State Department, Pentagon, and intelligence community who joined me on this mission.” Reads a tweet.

He served as US special representative for nearly three years and got the US-Taliban agreement signed but failed to make the Taliban and Afghan government reach an agreement.

Former Afghan officials and Afghan people criticize his mission though; the Taliban foreign ministry said that they had progress with Zalmay Khalilzad.
