Heart: A roadside bomb on Saturday killed four Afghan policemen when it ripped through their patrol vehicle in western Afghanistan, a provincial government official said.

"A police pick-up truck hit a roadside bomb planted by insurgents in Qaraghul area in Qadis district of western Badghis province," a provincial governor spokesman, Salahuddin Majeedi said.

"Unfortunately, all four policemen onboard were killed."

There was no immediate claim of responsibility, but roadside bombs are regularly planted by Taliban insurgents fighting a decade-long war against NATO-led foreign troops and Afghan government forces.

Afghan security forces are particular targets of the Taliban, as they prepare to take over full responsibility for security from 130,000 foreign troops by 2014.

But roadside bombs often kill civilians, with two consecutive bombings in the southern Afghan province of Helmand killing eight people on Thursday, including seven members of one family.
