Sri Lankan security forces have been accused of continuing to use torture, rape and other sexual violence against suspected members of the Tamil Tiger rebels by an international rights group.

Sri Lankan security forces went on red alert today, military officials said, securing a supply corridor into the restive east following a surge in attacks blamed on Tamil Tiger rebels that have endangered the country’s shaky cease-fire.

A suspected Tamil Tiger rebel detonated explosives at a police station in the Sri Lankan capital Colombo today, killing herself and four others, police said.
