SEOUL: A South Korean court Wednesday jailed seven protesters who threw firebombs at police, sparking a blaze that killed six people including a policeman. Two were sentenced to six years in prison, five were given five-year terms and two others received suspended jail sentences. They were found guilty of staging violent protests with firebombs when police in January raided a Seoul building scheduled for demolition but occupied by dozens of protesters. In dramatic scenes, a crane was used to drop police commandos onto the roof, sparking a confrontation with the masked protesters armed with firebombs, steel pipes, bricks and slingshots. Demonstrators protesting what they called inadequate compensation for residents had stored paint thinner on the roof to make the firebombs, and prosecutors said this fed the blaze.
