Roadside bomb in east Afghanistan kills policeman, civilian

An Afghan official says a roadside bombing in the country's east has killed a traffic policeman and a civilian.

Deputy police chief of Nangarhar province, Abass Sadat, says the explosion took place in Jalalabad, the provincial capital, on Wednesday. He says the explosion also wounded two civilians.

Sadat also says that the bomb was likely detonated by remote control and that it went off near a police checkpoint.

No one immediately claimed responsibility for the attack but Sadat blamed the Taliban.

Taliban attacks against both Afghan security forces and civilians have escalated across the country as part of the insurgents' warm-weather offensive.
