Pentagon says Kabul airport is secure, evacuation flights have resumed

State of play: Approximately 3,500 troops are on the ground at Kabul's airport as of Tuesday morning, with 4,000 expected to be there by the end of the day, according to officials.

• Approximately 700 to 800 people were evacuated on seven flights overnight, including 165 American citizens. The rest are a mix of special immigrant visa (SIV) applicants and foreign nationals.
• The Pentagon is aiming to have at least one flight per hour take off from Hamid Karzai International Airport when operations are fully running, with the expectation that 5,000 to 9,000 people can be evacuated per day.
• U.S. troops have experienced "no hostile interactions, no attack, no threat by the Taliban" during the evacuation operations, Maj. Gen. Hank Taylor, a Pentagon logistics expert, said during a press briefing Tuesday.

What to watch: The evacuation effort will continue until Aug. 31, the deadline for President Biden's full military withdrawal from Afghanistan. Asked why the U.S. couldn't keep evacuating Afghans into September if the airport is still secure, a Pentagon spokesman said that's a decision for the president.
