Officials in western Afghanistan say a roadside bomb has killed six police officers.
Authorities say a vehicle the police were riding in was destroyed when it hit the bomb Tuesday in the Obe district of Herat province.
The police were assigned to work as guards on a dam project.
There was no claim of responsibility, but similar assaults often are blamed on the Taliban.
Meanwhile, a Taliban offensive in southern Afghanistan has killed four police officers.
Officials say a large number of Taliban fighters attacked several security checkpoints in Helmand province.
