KEY POINTS
  • The Taliban have claimed victory over Afghanistan's last holdout province, but resistance groups there have vowed to keep fighting.
  • Fighting was continuing as of late Tuesday, according to a member of the National Resistance Front, who spoke to CNBC from Panjshir on condition of anonymity due to security risks.
  • A complete Taliban victory over the holdout Panjshir Valley would be a devastating and symbolic blow, regional experts say.
Taliban members patrol after they entered the Panjshir Valley, the only province the group had not seized during its sweep last month in Afghanistan on September 6, 2021.

The status of the Panjshir Valley in the east of Afghanistan remained unclear Tuesday, following Taliban statements that the militants had taken the last holdout province in the country even as anti-Taliban resistance members vowed to keep fighting. 

If the claims of victory are true, it means that the whole of Afghanistan is now under control of the Taliban, who through a series of stunning battlefield gains and Afghan military surrenders through July and early August took over the country of nearly 40 million as the U.S. withdrew its forces.
