In Sri Lanka, Human Rights Watch is calling on both the government and the Tamil Tigers to allow humanitarian aid to reach thousands of civilians trapped by fighting. In north Sri Lanka about 500,000 residents have been left with dwindling supplies of food and water and no ability to go to safe areas. About 40,000 people are believed to have fled their homes. Meanwhile, here in the United States, police have arrested 13 people on suspicion of conspiring to buy arms for the Tamil Tigers.
