The US has safely evacuated more than 5,500 American nationals from Afghanistan including about 50 people in the last day and there are nearly 250 Americans who are trying to leave the war-torn country, the State Department said.

Chaos has enveloped Kabul after Afghanistan`s government collapsed and the Taliban seized control on August 14. The Taliban insurgents stormed across the country, capturing all major cities in a matter of days, two weeks before the US was set to complete its troop withdrawal after a costly two-decade war. "Nearly 5,500 American citizens and likely more have been safely evacuated from Afghanistan since August 14. This includes an additional roughly 50 individuals in the last day," a State Department spokesperson said.
