The leader of Sri Lanka's Tamil Tiger rebels, Velupillai Prabhakaran, was shot dead while trying to flee government troops, a senior defence official told AFP .

Prabhakaran tried to flee the area in an ambulance along with two close aides, but was ambushed and killed, the senior defence ministry official said on condition he not be named.

A defence ministry statement later said that "senior leaders" who tried to escape in two vehicles but were "crushed."

It did not officially confirm or deny Prabhakaran's death, but said bodies were being identified. The military said his two deputies had been killed.

Earlier, the Sri Lanka military said that troops had killed three senior Tamil Tiger militants and found the body of Prabhakaran's son in mopping-up operations after the movement's defeat.

Brigadier Udaya Nanayakkara said some rebels continued to offer resistance as troops conducted "mopping-up operations" in the area.

He said security forces had found the body of Prabhakaran's 24-year-old son Charles Anthony during those operations.

The other senior figures were political chief B Nadesan, the head of the Tigers' defunct peace secretariat, S Puleedevan, and their eastern leader, S Ramesh, the defence ministry said.

The news about Prabhakaran's death came just a day after the LTTE said that its chief was still holed up in the war zone with his fighters.

In a dramatic announcement, the guerrillas admitted yesterday that their battle for an independent ethnic homeland had reached its "bitter end" - signalling Asia's longest running civil war was all but over.

"We have decided to silence our guns. Our only regrets are for the lives lost and that we could not hold out for longer," Selvarasa Pathmanathan, the Tigers' chief of international relations, said in a statement.

Victory to be announced tomorrow

He said the rebel leadership, including Tamil Tiger chief Prabhakaran, was still holed up in an area of less than 60 acres of jungle on the northeast coast, surrounded by government forces.

The island nation's hawkish president, Mahinda Rajapakse, was expected to announce in parliament on Tuesday that the decades-old war - one that left more than 70,000 dead in pitched battles, suicide attacks, bomb strikes and assassinations - had been won.

The capital Colombo, which has been frequently hit by Tiger suicide attacks over the past quarter century, was the scene of street celebrations which lasted well into Sunday night.

But Sri Lankan authorities are still determined to capture, kill or recover the body of Prabhakaran amid fears his escape could lead to an attempt to rebuild the Liberation Tigers of Tamil Eelam (LTTE) and a new cycle of guerrilla warfare.

"We have still not come across Prabhakaran and his senior leaders," defence spokesman Lakshman Hulugalle told reporters, dismissing speculation that he was dead and his body had been recovered.

Where is Prabhakaran?

Rebel official Pathmanathan, believed to be in hiding in a Southeast Asian nation, told Britain's Channel 4 news that Prabhakaran, who has been living underground since 1972, was still alive on Sunday along with 2,000 of his fighters.

The Sri Lankan government's moment of triumph has also come at the cost of thousands of innocent lives lost in indiscriminate shelling, according to the United Nations. The UN's rights body now wants a war crimes probe.

The International Committee of the Red Cross, the only neutral organisation that has been allowed to work in the war zone, has for its part described "an unimaginable humanitarian catastrophe."

But Sri Lanka has shrugged off the international pressure.

He said more than 63,000 people had crossed over into government territory in recent days, raising the total number of civilians who had fled the war zone since January to nearly 250,000.

The displaced are being moved into state-run "welfare villages" - camps ringed by barbed wire which are another source of international alarm. Rights workers, aid groups and journalists are also being denied free access to the north.

Meanwhile, Norway, the former negotiator in the conflict, said peace was far from won in Sri Lanka, despite the government's claims.

"The conflict is not resolved even if the battle has been won," said Minister of Environment and International Development Erik Solheim, calling on the authorities to "demonstrate generosity towards the Tamil population and grant Tamils autonomy."
