Evacuation flights restart from Kabul

US military flights evacuating diplomats and civilians from Afghanistan restarted on Tuesday after the runway at Kabul airport was cleared of thousands desperate to flee following the Taliban’s sudden takeover of the capital.

The number of civilians had thinned out, a Western security official at the airport told Reuters, a day after chaotic scenes in which U.S. troops fired to disperse crowds and people clung to a U.S. military transport plane as it taxied for take-off.

“Runway in Kabul international airport is open. I see airplanes landing and taking off,” Stefano Pontecorvo, NATO’s civilian representative, said on Twitter.

At least 12 military flights had taken off, a diplomat at the airport said. Planes were due to arrive from countries including Australia and Poland to pick up their nationals and Afghan colleagues.

As they rush to evacuate civilians, foreign powers are also assessing how to respond to the new rulers in Kabul and also how to deal with refugees trying to flee the country.

Former U.S. President George W. Bush, who launched a “war on terror” in Afghanistan following the Sept. 11, 2001, attacks, said the United States must move quickly to help Afghan refugees.

Turkish Foreign Minister Mevlut Cavusoglu said the country was in talks with all parties in Afghanistan, including the Taliban, and was positive on their statements since they took control.

Under a U.S. troops withdrawal pact struck last year, the Taliban agreed not to attack foreign forces as they leave.

U.S. forces took charge of the airport – their only way to fly out of Afghanistan – on Sunday, as the militants wound up a week of rapid advances by taking over Kabul without a fight, 20 years after they were ousted by a U.S.-led invasion.

Flights were suspended for much of Monday, when at least five people were killed, witnesses said. Media reported two people fell to their deaths from the underside of a U.S. military aircraft after it took off.

U.S. President Joe Biden defended his decision to withdraw U.S. forces after 20 years of war – the nation’s longest – which he described as costing more than $1 trillion.

But a video of hundreds of desperate Afghans trying to clamber on to a U.S. military plane as it was about to take off could haunt the United States, just as a photograph in 1975 of people trying to get on a helicopter on a roof in Saigon became emblematic of the humiliating withdrawal from Vietnam.

Biden said he had to decide between asking U.S. forces to fight endlessly or follow through on a withdrawal agreement negotiated by his predecessor, Republican Donald Trump.

“I stand squarely behind my decision,” Biden said. “After 20 years I’ve learned the hard way that there was never a good time to withdraw U.S. forces. That’s why we’re still there.”

Facing criticism from even his own diplomats, he blamed the Taliban’s takeover on Afghan political leaders who fled and its army’s unwillingness to fight.
