COLOMBO (AFP) - Sri Lankan warplanes bombed a rebel arms storage base, while artillery duels between security forces and Tiger rebels killed 29, the defence ministry said Sunday. Air force fighter jets bombed a rebel ammunition storage dump in guerrilla-controlled Mullaittvu area on Saturday, the military said, adding that "pilots confirmed sporadic explosions" after the raid. Government troops also traded fire with Tiger rebels across the Vavuniya, Mannar and Wanni regions, killing 29 guerrillas on Saturday, the statement said, placing troop casualties at two soldiers injured. There was no immediate comment from the Liberation Tigers of Tamil Eelam (LTTE), who have been locked in armed combat with the Sinhalese dominated government for a separate state for minority Tamils.
