Islamabad  - At least two policemen were killed Wednesday in a suicide bombing in Pakistan's North-West Frontier province, media reports and officials said.

The bomber rammed an explosives-laden vehicle into a police checkpoint in the Tangi area of the province's Charsadda district, said Mohammad Yar, the district's police officer.

Yar declined to give casualty figures, explaining the dead and injured were still being moved to hospital. "When the process is completed we will give the figure," he told German Press Agency dpa via telephone.

Urdu-language Geo television cited official sources as saying two policemen were killed. (dpa)
