The Red Cross is warning of a catastrophe as the Sri Lankan government launches a "final" assault against the rebel Liberation Tigers of Tamil Eelam (LTTE ), who ignored the government's calls for surrender and are now cornered in a small piece of coastal territory.

Tens of thousands of civilians are caught in the crossfire, although some 50,000 others escaped to government-controlled areas. Both the Tamil Tigers and the Sri Lankan government have been accused of humanitarian abuses.

The Tamil Tigers have long fought for an independent state for Sri Lanka's Tamil ethnic minority, which is often at odds with the majority Sinhalese community. Seen by some as a prototype for modern terrorism, the Tamil Tigers pioneered the suicide bomb jacket and the use of women in suicide attacks.

The 25-year civil war is one of Asia's longest-running conflicts, and was more deadly than the war in Afghanistan last year.
