Taliban on Wednesday afternoon warned the US and NATO to stick to the agreement of troops withdrawal on May 1 and said if the Doha agreement is not adhered to problems will be “compounded” and those in breach of the deal will “be held liable”.

In a series of tweets, Zabihullah Mujahid, a Taliban spokesman, said: “The Islamic Emirate of Afghanistan seeks the withdrawal of all foreign forces from our homeland on the date specified in the Doha Agreement.

“If the agreement is adhered to, a pathway to addressing the remaining issues will also be found.

“If the agreement is breached and foreign forces fail to exit our country on the specified date, problems will certainly be compounded and those whom failed to comply with the agreement will be held liable.”

This comes ahead of an expected official announcement by US President Joe Biden that troops with be pulled out by September 11 – the 20th anniversary of the 9/11 attacks on the United States.

US Secretary of State Antony Blinken meanwhile said in Brussels on Wednesday that the coalition of NATO-led troops in Afghanistan will leave the country in coordination with a planned U.S. withdrawal by September 11.

Blinken said it was time for NATO allies to make good on its mantra that allies went into Afghanistan together and would leave together.

“I am here to work closely with our allies, with the (NATO) secretary-general, on the principle that we have established from the start: In together, adapt together and out together,” Blinken said in a televised statement at NATO headquarters.

“We will work very closely together in the months ahead on a safe, deliberate and coordinated withdrawal of our forces from Afghanistan,” Blinken said, standing alongside NATO Secretary-General Jens Stoltenberg,
