Seven people are confirmed to have been killed amid chaotic scenes at Hamid Karzai International Airport as US forces try to pull the remaining officials out of Afghanistan.

In a separate incident, a US soldier was shot at the airport. No further details were available immediately.
Thousands of Afghans rushed onto the tarmac of Kabul’s international airport Monday, some so desperate to escape the Taliban capture of their country that they held onto an American military jet as it took off and plunged to death.
CNN reporter Nick Paton Walsh described the scene at the airport as “chaotic” on Monday as thousands of Afghan people tried to board flights out of the country.
Taliban forces had commandeered Afghan military vehicles and were trying to keep crowds from rushing through the fences.
Footage captured on Monday showed people clinging on to a US military aircraft as it took off from the airport.
