Air Force investigating takeoff deaths at Kabul airport

• Videos showed people swarming U.S. military aircraft as they were attempting to take off on Monday.
• At least seven people were killed during the chaos at the airport, including several who plunged to their deaths after clinging on to a U.S. military jet that took off from the runway.
• The U.S. sent an additional 1,000 troops to the airport to help secure the runway.

The big picture: The Air Force did not disclose how many people died but said human remains were found in a plane’s wheel well after it landed at al-Udeid Air Base in Qatar, according to AP.

• The U.S. is still attempting to process visas and evacuate thousands of Afghan refugees who aided U.S. and coalition forces and may face retaliation from the Taliban.
• The Pentagon said Tuesday that the airport was again secured and that evacuations resumed.
• Pentagon spokesperson John Kirby defended the chaos at the airport Tuesday, saying "no plan survives first contact."
