Taliban celebrate 'complete independence' as last US troops leave Afghan

America's longest war took the lives of nearly 2,500 US troops and an estimated 240,000 Afghans, and cost some $2 trillion

Celebratory gunfire echoed across Kabul as Taliban fighters took control of the airport before dawn on Tuesday following the withdrawal of the last US troops, ending 20 years of war that left the Islamic militia stronger than it was in 2001.

Shaky video footage distributed by the Taliban showed fighters entering the airport after the last US troops took off a minute before midnight, marking the end of a hasty and humiliating exit for Washington and its NATO allies.

"The last US soldier has left Kabul airport and our country gained complete independence," Taliban spokesman Qari Yusuf said, according to Al Jazeera
