World leaders unblocked $15 billion in funds to help Libya's victorious rebels rebuild their shattered country as fugitive strongman Moamer Kadhafi called for guerrilla warfare.
Forty-two years to the day since Kadhafi took power in a coup, senior envoys from over 60 countries Thursday met the leaders of the revolution that overthrew him to endorse the fledgling regime and offer practical support.
But in the meeting in Paris, they also put the leaders of the rebels' National Transitional Council (NTC) on notice to pursue a path of reconciliation, even as Kadhafi issued a message of defiance from his desert hiding place.
"Prepare yourselves for a gang and guerrilla war, for urban warfare and popular resistance in every town... to defeat the enemy everywhere," he said in an audio tape aired on Arab satellite television.
The Paris guestlist was a victory in itself for the NTC, as once sceptical Russia and China and Libya's reluctant neighbour Algeria agreed to back the new administration.
French President Nicolas Sarkozy, the rebels' most prominent backer from the outset, announced that billions in Libyan assets frozen abroad will now be unblocked.
"Around $15 billion have been immediately unfrozen... we want to give back to the Libyans the money that was frozen and that was stolen from them," he said.
Speaking alongside the rebel leaders, Sarkozy urged the NTC to begin a "process of reconciliation and forgiveness."
NTC president Mustafa Abdel Jalil said the Libyan people "proved their courage and their determination" in their fight to topple Kadhafi, but he also pleaded for stability.
"Now everything is in your hands," he said in a message to the Libyan people. "It's up to you to accomplish what we promised: stability, peace and reconciliation."
The rebels have issued an ultimatum for Kadhafi and his followers to surrender, and have amassed troops around his hometown of Sirte for a final battle.
At the Paris conference, NATO Secretary General Anders Fogh Rasmussen said the alliance would continue its six-month operation in Libya for as long as the civilian population was in danger.
Kadhafi, who might once have marked his coup anniversary with pomp and ceremony, was reduced to releasing his latest bluster on tape, vowing: "We will not surrender. We are not women and we are going to keep on fighting."
In Tripoli, rebel commander Abdullah Naqir announced the creation of the council of Tripoli's revolutionaries to defend the capital, restore order and hunt down Kadhafi loyalists.
While the mood in Paris was upbeat, US Secretary of State Hillary Clinton sounded a note of caution, urging the rebels to beware of extremism in their own ranks and prevent weapons from falling into the wrong hands.
"The international community, led by the UN, needs to help the Libyan people and its leaders pave a path to a sustainable, inclusive democracy that banishes violence as a political tool and promotes tolerance," she said.
UN chief Ban Ki-moon said he would work with the Security Council to agree terms for an immediate United Nations mission to deal with a possible humanitarian crisis and help rebuild the state.
"Our most immediate challenge is humanitarian," he said.
"Roughly 860,000 people have left the country since February, including skilled guest workers. Public services are under severe strain... There is a major water shortage."
Russia -- which had opposed NATO military support for the rebels -- said it recognised the NTC as Libya's "ruling authority".
China, which also had reservations about the air campaign, did not go so far, but said it respected the NTC's "significant position."
Continental heavyweight South Africa, however, continued to snub the NTC. President Jacob Zuma boycotted the talks and said he was "not happy" with NATO's campaign. The African Union has not recognised the NTC.
The Algerian turnabout may prove of more immediate practical help in cutting off a potential Kadhafi escape route.
Libya's larger neighbour has been accused of supplying Kadhafi with arms and, after members of the fallen leader's family fled there, it was seen as a likely escape route for the strongman and his loyal sons.
But Algeria's Foreign Minister Mourad Medelci welcomed the NTC promise to set up a "government representative of all regions" and added: "When it has done so, we'll recognise it."
Kadhafi and his son Seif al-Islam have gone underground since rebels stormed into Tripoli on August 20.
"If they want a long battle, let it be long. If Libya burns, who will be able to govern it? Let it burn," declared Kadhafi in his statement.
Rebel officials say Kadhafi may be in the town of Bani Walid, south of the capital and still held by loyalist troops, but other reports suggest he could be in his hometown Sirte or Ghadames, near the Algerian border.
A western diplomat meanwhile said the UN Security Council could pass a resolution lifting some sanctions against Libya as early as next week.
