After a week-long "reduction in violence," the US and Taliban have signed an agreement Saturday, which would set into motion the drawdown of US troops from Afghanistan and potentially pave the way to ending America's longest-fought war.

Iran Press/Asia: The agreement was signed in Doha, Qatar, by US Special Representative for Afghanistan Reconciliation Zalmay Khalilzad -- the chief US negotiator in the talks with the Taliban -- and Mullah Abdul Ghani Baradar. Secretary of State Mike Pompeo witnessed the signing.

Speaking at the ceremony, Pompeo said the US "will closely watch the Taliban's compliance with their commitments, and calibrate the pace of our withdrawal to their actions," CNN reported.

"This is how will ensure that Afghanistan never again serves for international terrorists," Pompeo claimed.

Secretary of Defense Mark Esper was in Kabul, Afghanistan, on Saturday for a joint declaration ceremony with Afghan President Ashraf Ghani.

According to Afghanistan's national security adviser Hamdullah Mohib, the joint US-NATO-Afghan declaration includes an 18-month withdrawal of foreign troops.

"But it is conditional on the agreement between the Taliban and the United States. If those conditions are not met, this date will also change," he said.
