Violence erupted at the Kabul airport as US forces shot and killed two armed men who fired on them Monday, according to a US defense official, as the US resumed temporarily suspended operations at the airfield after clearing crowds off the runways.

As the chaos at the airport and the tumultuous US withdrawal continued, the White House announced that President Joe Biden would address the nation about the state of affairs in Afghanistan on Monday afternoon.

US officials reported that they believe the shooting at the airport was an isolated incident and have not verified whether the armed men were Taliban. But they also have an unconfirmed report that one US troop has been injured by a gunshot in another incident at the airport, the official said.

A witness told the two men shot and killed by US forces were Taliban fighters and that a third fighter was injured. According to the witness, the Taliban fighters showed up at an airport entrance just as multiple high-profile foreign and Afghan vehicles were trying to enter the airport through the same entry.

The witness says that in the confusion, the Taliban fighters shot into the air to try to clear the gate and that the US military fired back, killing two of the men and injuring a third.
