This is Ahmad Massoud’s exceedingly rugged turf. The Taliban claimed to have taken it yesterday.
My money is on Tajikistan as the striker, since the area has the highest concentration of ethnic Tajiks in Afghanistan. The Tajiks also have much of Afghanistan’s former air force, complete with the defecting pilots who came with it.

Multiple unconfirmed reports of airstrikes against the Taliban in Panjshir valley. Only speculation regarding what force made the strikes. https://t.co/Aeaw3tsqHS
