Gut-wrenching moment distressed mothers in sewage drains hand their children over a fence to Aussie soldiers just hours before the Kabul Airport blast killed 60 people

Harrowing footage has captured the moment desperate mothers handed their children to Australian soldiers in the hours before two blasts at Kabul Airport killed 60 people.

Video showed families passing young children and their belongings over a barbed wire fence to Australian soldiers outside the airfield on Thursday.

At 6pm local time, at least 60 Afghans and 12 US military personnel were killed when two suicide bombers attacked the crowds trying to flee the city after its fall to the Taliban 10 days ago.

No Australians troops have been killed in the two deadly bomb blasts, with the ADF withdrawing their soldiers during a final airlift earlier in the day.

The Afghan affiliate of Islamic State known as Islamic State Khorasan (ISIS-K) has claimed responsibility for the attacks. 

'It's a horrible, horrible day,' Defence Minister Peter Dutton told the Today show on Friday.

'I just grieve, like every decent person would, at the loss of life and in particular for us, the loss of the American lives.'

Australia has helped about 4,000 people escape Afghanistan, which has descended into chaos after the Taliban rapidly seized control following a US decision to withdraw from the country after 20 years. 

Mr Dutton said US troops provided security for thousands of Australian citizens and visa holders who escaped through the Abbey Gate and the Baron hotel where the blasts were detonated.

'Our troops will be devastated by the loss of their comrades. These are people they've worked alongside over the course of the last week,' he said.

'It's remarkable how many people they have brought out, that they've saved, particularly women and children, but everybody is devastated by this.'

As well as Australia, Norway, Poland, Holland and Canada have all stopped evacuating citizens. 

US General Kenneth F. McKenzie said the US would keep evacuating its citizens despite Thursday's attack and despite an 'imminent' threat of more attacks. 

US President Joe Biden has promised to hunt down and destroy the terrorists in the double suicide attack.

He paid tribute to the 'selfless heroes' who died helping vulnerable people to safety, but delivered a stern warning to the people responsible. 

'For those who carried out this attack, as well as anyone who wishes America harm, know this: We will not forgive, we will not forget,' he said in an address at the White House. 

'We will hunt you down and make you pay.' 

Biden has been under intense pressure to justify his decision to withdraw by August 31, after the way in which the Taliban raced across the country and captured the capital.

That pressure reached fever pitch on Thursday as Republicans called for Biden's resignation or impeachment.

Two suicide bombers and gunmen attacked crowds of Afghans flocking to Kabul's airport Thursday, transforming a scene of desperation into one of horror in the waning days of an airlift for those fleeing the Taliban takeover

Administration officials have been forced to negotiate with Kabul's new rulers in order to ensure Westerners and vulnerable Afghans could reach the airport.

Warnings had grown in recent days that ISIS-K was planning a major attack. 

Biden said the US would continue with the operation to rescue another 1000 Americans believed to still be in Kabul.

'We will not be deterred by terrorists,' he said. 'We'll not let them stop our mission.'
