Tamil rebels trapped in a tiny enclave of northern Sri Lanka have declared a ceasefire, a rebel spokesman says.
The Tamil Tigers (LTTE) had given up their fight against a major government offensive and "decided to silence our guns", he said on a pro-Tamil website.
"This battle has reached its bitter end," said Selvarasa Pathmanathan, the Tigers' chief of international relations, in a statement on Tamilnet.
President Mahinda Rajapaksa has already claimed victory in the 26-year war.
A later statement on the Tamilnet website appeared to modify the rebel position.
Mr Pathmanathan said the LTTE was "prepared to silence its guns if that is what
needed by the international community to save the life and dignity of the Tamil people".

"In the past 24 hours, over 3,000 civilians lie dead on the streets while another 25,000 are critically injured with no medical attention," said the statement.
A senior Sri Lankan media spokesman told the BBC the government did not respond to documents posted on Tamilnet or take them seriously.
Lakshman Hulugalle said the government was waiting for an official "request" from the LTTE.
In contrast, Sri Lanka military officials said earlier that all the civilians who had been trapped in Sri Lanka's northern war zone had escaped.
The government rejected the ceasefire calls, saying that as all trapped civilians had now fled from the area of conflict, there was no reason to stop its offensive.Army spokesman Brig Udaya Nanayakkara said some 50,000 ethnic Tamils had fled the area over the past three days.
Like all accounts from the war zone, neither claim can be independently verified.
Fighting is still continuing, but there has been no sign of the Tigers' leader, Velupillai Prabhakaran, the Sri Lankan defence minister told the BBC.
For months, tens of thousands of Tamil civilians have been trapped in the war zone, vulnerable to bombardments as the government and Tamil Tiger rebels fought bitterly.
The United Nations says they were being forcibly kept there by the rebels and that more than 6,000 have been killed since January.
The UN has told the BBC the army figures reinforced its view that Sri Lanka's authorities were ill-prepared for the huge influx of internally displaced people.
Refugee camps inland are already badly strained accommodating the huge numbers of those who have fled the conflict.
Both the UN and Western governments have called on Sri Lanka to exercise restraint in its pursuit of a military victory over the Tigers.Despite President Rajapaksa's claim of military victory on Saturday, senior officials told the BBC that fighting was still continuing in the area where the LTTE leaders were said to be cornered.
A military spokesman has told the BBC the last remnants of the rebels are trapped in 1.5 square kilometres of jungle. Again, his assertion cannot be verified.
More than 70,000 people have died in the bitter war for a Tamil homeland.
Sri Lanka's army said earlier 70 rebels had been killed trying to escape from a tiny enclave where they are holed up in the island's north-east.
The army says it has cut off rebel access to the sea.
Brig Udaya Nanayakkara said a "process of identification" was going on to identify the 70 rebels killed while trying to cross a lagoon in six boats.
President Rajapaksa is expected to give a nationally televised news conference in parliament on Tuesday, when reports suggest he may officially declare the war over.
