KABUL/GENEVA/LONDON - Mullah Abdul Ghani Baradar, political chief of Afghanistan's Taliban, said they intend to establish ties with all countries around the world, denying reports that they do not want ties with the US.

"The Islamic Emirate of Afghanistan wants diplomatic and trade ties with all countries, particularly with the United States of America," Baradar wrote on social media platform Twitter on Saturday.

"We never talk about cut of trade ties with any countries. Rumor about this news has been propaganda. It is not true," he said.

The vast majority of Afghans were not able to leave the country through regular channels, Mantoo said, adding that some 200 UNHCR colleagues, both national and international, remained in Afghanistan.

"This is one of the largest, most difficult airlifts in history, and the only country in the world capable of projecting this much power on the far side of the world with this degree of precision is the United States of America," said Biden, who has been widely criticized on the botched pullout, in a televised speech from the White House.

Biden said he has "seen no question of our credibility from our allies around the world."

"And all our allies have agreed with that ... every one of them knew and agreed with the decision I made to end - jointly end - our involvement in Afghanistan," said Biden with Vice-President Kamala Harris, Secretary of State Antony Blinken, Secretary of Defense Lloyd Austin and National Security Adviser Jake Sullivan standing behind him.

Calling the past week "heartbreaking," Biden said the United States has made "significant progress" and evacuated from Afghanistan over 18,000 people since July and 13,000 since Aug 14.

He pledged to use the full force of the US military to complete the withdrawal and bring Americans and their Afghan allies who assisted the United States in the 20-year conflict to safety.

Meanwhile, British Prime Minister Boris Johnson said Friday that Britain will work with the Taliban "if necessary," as the group has regained the control of Afghanistan

This is Biden's second press conference at the White House since the Taliban took control of the Afghan capital of Kabul last weekend.

The world was shocked to see scenes of chaotic evacuation at the Kabul airport.

In his speech on Monday, Biden said Kabul's fall to the Taliban came much sooner than Washington had anticipated.

UK to work with Taliban 'if necessary'

Meanwhile, British Prime Minister Boris Johnson said Friday that Britain will work with the Taliban "if necessary," as the group has regained the control of Afghanistan.

"What I want to assure people is that our political and diplomatic efforts to find a solution for Afghanistan - working with the Taliban, of course, if necessary - will go on," Johnson told reporters.

He said the situation at the Kabul airport, where thousands of Afghans gathered in hopes of boarding an evacuation flight, was getting "slightly better" and he saw "stabilization."

Britain has been able to evacuate about 2,000 people, including British nationals and Afghans who worked with Britain, since Thursday, the prime minister said.
