Mullah Dowran, a regional Taliban commander in eastern Afghanistan, has told Al Jazeera that the organisation is now targeting Afghan security forces.
"We announced we would forgive them many times. We showed them leniency many times in the fight. We tried to make American targets the priority, but the damage created by Afghan forces has become more and more every day. Now they are our priority," Dowran said.
The Taliban are not only targeting police and soldiers, but also seeking out their family members in a campaign to persuade them to defect.
