WATCH: Taliban Take Over Kabul International Airport After U.S. Army Evacuation

As the last US military plane left Kabul Monday night ending America’s 20-year-long presence in Afghanistan, Taliban soldiers were heard celebrating with gunfire before they stormed and took over the airport.

Videos shared by an LA Times correspondent showed Taliban fighters wearing US army uniforms entering the former US military hanger, inspecting Chinook helicopters left behind and taking an inventory of equipment left behind.

Earlier this month, Republican Representative Michael McCaul told Reuters, "We have already seen Taliban fighters armed with U.S.-made weapons they seized from the Afghan forces. This poses a significant threat to the United States and our allies."

According to a report, the US military disabled its armored vehicles, equipment and aircraft before leaving the Hamid Karzai International airport at Kabul, the US army’s last hold. The military kept the equipment operational until the end of the mission Monday before boarding the last flight. The US military left behind 70 Mine Resistant Ambush Protected Vehicles, 73 aircraft and 27 Humvees tactical vehicles at the Kabul International Airport.

“It’s a complex procedure, complex and time-intensive procedure to break down those systems so we de-militarized those systems so that they’ll never be used again, and we just felt it more important to protect our forces than to bring those systems back,” said Marine Corps Gen. Kenneth F. McKenzie Jr., reported CNN.

Taliban fighters reportedly started securing the perimeters of the airport, removed heavy barricades and unlocked the airport gates after the US military evacuation, reported The Guardian. At one point, fighters walked the airport runway to mark their victory.

“After 20 years we have defeated the Americans. They have left and now our country is free,” said Mohammad Islam, a Taliban guard at the airport carrying a Kalashnikov rifle, reported the outlet. “It’s clear what we want. We want Shariah (Islamic law), peace and stability.”

US president Joe Biden thanked US forces serving in Afghanistan for the final retrograde mission in a statement Monday. President Biden stated that on the recommendation of Joint Chiefs and commanders on the ground, the US will end its airlift mission as planned and will not extend US presence in Afghanistan beyond Aug. 31 deadline.

“The past 17 days have seen our troops execute the largest airlift in US history, evacuating over 120,000 US citizens, citizens of our allies, and Afghan allies of the United States,” read President Biden's statement. “They have done it with unmatched courage, professionalism, and resolve. Now, our 20-year military presence in Afghanistan has ended.”
