Five policemen were also wounded and the Taliban seized all the weapons and ammunition from the security before reinforcements arrived, he said. "They arrived there late, fought back and managed to get the checkpoint under control," he added.
Earlier on Monday, the Taliban targeted a local pro-government militia in a village in northern Samangan province, killing 10 people there, including a woman, said Sediq Azizi, spokesman for the provincial governor.
Four people were also wounded in that attack, in Samangan's Dara-I Suf district, he said.
According to Azizi, the Taliban targeted local villagers, including women and children. As the area is very remote, the villagers have their own militia to provide security for their area and defend their homes from the insurgents.
The Taliban claimed both attacks in statements to the media.
