A suspected suicide bomb exploded outside Kabul airport on Thursday, killing at least 13 people including children, a Taliban official said.

The official said many Taliban guards were wounded. Thousands of people have been gathering outside the airport in recent days to flee the country after Taliban take over.

As per an official of the United States, US service members were among the wounded. The official was citing an initial report and cautioning that it could change. He said there were casualties but did not know how many or of what nationality.

"Our guards are also risking their lives at Kabul airport, they face a threat too from the Islamic State group," said a Taliban official.

The blasts came as the August 31 deadline loomed for the United States to withdraw its troops, and for Western countries to end their massive airlifts.

The "complex attack" near the airport caused a number of US and civilian casualties, Pentagon spokesman John Kirby said in a tweet.

US President Joe Biden had earlier cited an "acute" terrorist threat from the regional chapter of the Islamic State jihadist group.

Kabul airport terror attack created chaos at the airport already thronged by hundreds of people wanting to escape the country.

NATO Secretary General Jens Stoltenberg said that the allied forces should continue to evacuate as many vulnerable people as they can from Kabul despite what he branded a "horrific terrorist attack".

Despite security warnings, huge crowds of people desperate to flee the Taliban continued to throng the airport, their bid for a way out becoming increasingly anxious ahead of next Tuesday's deadline set by Biden to end evacuations and withdraw troops
