Taliban forces seized an Afghan military helicopter after they captured the Shindand Air Base in Herat, northeastern Afghanistan, according to reports.
Herat, which is Afghanistan’s second-largest city, was mostly seized by Taliban insurgents on Friday. They also succeeded in capturing Ismail Khan, the veteran local commander leading militia resistance there, according to local officials.
Earlier this week, the group was also reportedly seen next to a Mi-35 attack helicopter that was abandoned by government forces at the airport in Herat.
The seizure comes as the group took control of Afghanistan’s second and third-largest cities, with fears that an assault on Kabul, the capital of the nation, could be just days away.
After an onslaught lasting a mere two weeks, the Taliban has captured half the country’s provincial capitals and over two-thirds of its territory, a stunning collapse for government forces that Western powers have spent two decades training and equipping.
While Kabul isn’t directly under threat yet, the resurgent Taliban were battling government forces in Logar province, some 50 miles (80 kilometers) from the capital.
The U.S. military has estimated that Kabul could come under insurgent pressure within 30 days and that the militant group could overrun the rest of the country within a few months.
