Taliban have moved into government buildings in Aibak, a provincial capital between the northern city of Mazar-i-Sharif and Kabul and tightened their grip on the Afghan territory. "Afghan leaders have to come together," Biden says, saying the Afghan troops outnumber the Taliban and must want to fight. The US president says he does not regret his decision to withdraw US troops, noting that Washington has spent more than $1 trillion over 20 years and lost thousands of troops. Taliban now controls approximately 65 per cent of the Afghan territory.
