The Red Cross says its staff in Sri Lanka are witnessing an "unimaginable humanitarian catastrophe" in the area where troops have trapped Tamil Tigers. The agency says a ferry loaded with aid has been unable to reach the battered north-eastern coastal strip for three days because of fighting.
There are also reports that staff have quit the last hospital in the war zone.
A senior UN envoy is on his way to Sri Lanka to try "to help resolve the humanitarian situation", the UN says.
The UN says about 50,000 civilians are trapped in the war zone, although Colombo disputes this figure. The government has rejected international calls to stop its offensive against the Tamil Tiger rebels, saying it would give them time to recover. Now that it has trapped the Tamil Tigers, it hopes to soon end the 25-year-old civil war. cmc¡¡audio rca wbt audio rca cmc rca plugs wbt rca plugs cmc rca jacks wbt rca jacks SATELLITE IMAGERY
