Correct Answer : Kandahar
The Taliban claimed 13-08-2021 to have captured Kandahar, Afghanistan's second-largest city, which would leave just the capital and pockets of other territory in the government's hands.
"Kandahar is completely conquered. The Mujahideen reached Martyrs' Square in the city," a Taliban spokesman tweeted on an officially recognised account -- a claim backed by a resident, who told AFP government forces appeared to have withdrawn en masse to a military facility outside the city.
