Taliban commanders are set to meet former governors and bureaucrats in more than 20 of Afghanistan's 34 provinces over the next few days to ensure their safety and seek cooperation, a Taliban official has told Reuters.

"We are not forcing any former government official to join or prove their allegiance to us, they have a right to leave the country if they would like," the official, who spoke on the condition of anonymity, said.

"We are seeking complete clarity on foreign forces' exit plan," the Taliban official added. "Managing chaos outside Kabul airport is a complex task." 

The Taliban on Sunday blamed the U.S. for the airport chaos, according to an AFP report.

"America, with all its power and facilities... has failed to bring order to the airport. There is peace and calm all over the country, but there is chaos only at Kabul airport," said Amir Khan Mutaqi, a Taliban official. 

The U.S. forces now control interior sections of the Kabul airport.
