Local officials of western Farah province said that Afghan Local Police (ALP) commander, Malam Jan, and two fellow police officers were killed by a roadside bomb on Friday afternoon in Bala Boluk district of the province.
Three other police officers were injured by the blast.
The incident took place in the Bala Boluk district when the police officers were on a patrol and their vehicle struck a roadside bomb, said Abdul Rahman Zhwandon, a Provincial Police Chief Spokesman.
The victims have been taken to a nearby hospital for emergency care.
The Taliban claimed responsibility for the blast, which occurred on the same day as a Taliban-claimed suicide attack in Kabul that targeted an international compound on Jalalabad road. The Kabul attack, however, only resulted in civilian casualties, including women and children.
