NATO has carried out more heavy air raids in and around the Yugoslav capital, Belgrade.

Serbian media reports say a hospital near the centre of Belgrade was hit, killing at least three people.

Witnesses say there were four big blasts in the city centre, and others in the suburbs.

Orange flashes lit up the night sky, and anti-aircraft missiles were fired.

Serbian media reports said a chemical plant at Baric, twenty-five kilometres to the southwest was targetted, as well as a power station and a water purification plant serving the capital.

Some reports describe the raids as the heaviest since the Chinese embassy in Belgrade was bombed nearly two weeks ago.
