The Afghan government's operation to recapture the city is expected to start in the coming hours, the BBC reported, citing a police spokesman.
According to media and police reports, dozens of combatants and civilians were killed during the Taliban offensive on Kunduz.
Afghanistan has been plagued by an ongoing Taliban insurgency since the early 1990s. The militants are notorious for staging attacks against civilian and state targets in Afghanistan and Pakistan, seeking to establish sharia law in the territories under its control.
The Taliban military movement launched a large-scale offensive in Afghanistan in April, despite continuous attempts by the country’s authorities to resume peace talks. In May, the militants surrounded the city of Kunduz.
