Taliban kill 9 Afghan security personnel in checkpoint raids: authorities
The militants launched simultaneous raids on the checkpoints in Kunduz, a region bordering Tajikistan that has seen regular clashes between the insurgents and government forces.
The Taliban did not offer any immediate comment.
In a separate incident on Friday, the Taliban used a drone to drop a bomb on an Afghan military base in Kunduz city, army spokesman Abdul Hadi Nazari said, adding that there were no casualties.
However, the bomb did damage a military helicopter, another Afghan source said on condition of anonymity.
The Taliban have deployed small drones to drop bombs on government forces in other recent attacks.
Afghan security officials say the insurgents have largely used hobby drones rigged with explosives.
In late October, they reportedly used a drone to bomb the compound of the governor of Kunduz province.
In recent months, violence has surged across several provinces of Afghanistan, even as the Taliban and government engage in peace talks to end the war.
