Bahrain Mirror (AP): Bahrain says a police officer has been killed and two others were seriously wounded in a gasoline bomb attack in the tiny island kingdom.

The Interior Ministry announced the officer's death Saturday night, saying the attack happened in the village of Karbabad. It said an investigation into the attack was ongoing as locals said a large security presence had gathered around the area.

The ministry did not elaborate on who throw the bomb, beyond calling it a "terrorist act." Protesters in Bahrain have thrown similar gasoline bombs in skirmishes with authorities.

Bahrain, home to the U.S. Navy's 5th Fleet, has seen low-level unrest since 2011 Arab Spring-inspired protests there by the kingdom's majority-Shiite population seeking more political power from the island's Sunni rulers.
