MANAMA, Bahrain — Bahrain's Interior Ministry says three policemen have been wounded by an explosion west of the capital Manama.

The ministry's statement, carried by the official Bahrain News Agency, says the "terror blast" late Friday targeted a security patrol in the predominantly Shiite village of Bani Jamra.

Anti-government activists primarily drawn from Sunni-ruled Bahrain's Shiite majority frequently clash with police, and hard-line protesters have at times used improvised explosives.

A policeman and a civilian were killed in separate explosions earlier this month.
