HERAT, Afghanistan (AFP) -- A remote-controlled bomb exploded near a western military convoy in western Afghanistan Sunday, killing two Afghan civilians, police said, in a new attack blamed on the Taliban.

The bomb exploded as the men, believed to be police force trainers, passed by the convoy on the outskirts of the western city of Herat, provincial police commander Mohammad Ayoob Salangi told reporters near the explosion site.

"Two of our countrymen were martyred and another wounded. It was a roadside bomb exploded by the enemies of Afghanistan," the police chief said.

The Taliban movement that was in government between 1996 and 2001 is waging an insurgency that relies on roadside and suicide bomb attacks which target mainly foreign and Afghan security forces but kill more civilians.
