Pech River Valley in eastern Afghanistan, once considered by the Americans as being central to their strategy, is now under the control of the Taliban.

The US troops pulled out after years of fighting for control of the area - a Taliban stronghold - that had led to mounting casualties.

Al Jazeera's Hashem Ahelbarra has this exclusive report on the Taliban patrol unit that has taken over this strategic base.
