Muammar Gaddafi vowed to die in Libya as a martyr in an angry television address on Tuesday, as rebel troops said eastern regions had broken free from his rule in a burgeoning revolt.
"I am not going to leave this land, I will die here as a martyr," Gaddafi said on state television, refusing to bow to calls from his own diplomats, soldiers and protesters clamouring in the streets for an end to his four decades at the helm.
"I shall remain here defiant," said Gaddafi.
Earlier, witnesses streaming across the Libyan border into Egypt said Gaddafi was using tanks, warplanes and mercenaries in an effort to stamp out the growing rebellion.
"All the eastern regions are out of Gaddafi's control now ... The people and the army are hand-in-hand here," said the now former army major Hany Saad Marjaa.
The White House offered its condolences for the "appalling violence" in Libya and said the international community had to speak with one voice on the crisis.
The U.N. refugee agency meanwhile urged Libya's neighbours to grant refuge to those fleeing the unrest, which was triggered by decades of repression and popular revolts that toppled leaders in Tunisia and Egypt.
On the Libyan side of the border with Egypt, anti-Gaddafi rebels armed with clubs and Kalashnikov rifles welcomed visitors. One man held an upside-down picture of Gaddafi defaced with the words "the butcher tyrant, murderer of Libyans".
Hundreds of Egyptians flowed in the opposite direction on tractors and trucks, taking with them harrowing tales of state violence and banditry.
In the eastern town of Al Bayda, resident Marai Al Mahry said that 26 people including his brother Ahmed had been shot dead overnight by Gaddafi loyalists.
"They shoot you just for walking on the street," he said, sobbing uncontrollably as he appealed for help.
Protesters were attacked with tanks and warplanes, he said.
"The only thing we can do now is not give up, no surrender, no going back. We will die anyways, whether we like it or not. It is clear that they don't care whether we live or not. This is genocide," said Mahry, 42.
Human Rights Watch said 62 people had died in clashes in Tripoli in the past two days, on top of its previous toll of 233 dead. Opposition groups put the figure far much higher. U.N. rights chief Navi Pillay said the killing could amount to crimes against humanity and demanded an international probe.
The revolt in Libya, the third largest oil producer in Africa, has driven oil prices to a 2 1/2 year high above $108 a barrel, and OPEC said it would produce more crude if supplies from member Libya were disrupted.With no end in sight to the crisis, refugees fled to Egypt."Five people died on the street where I live," Mohamed Jalaly, 40, said at Salum on his way to Cairo from Benghazi. "You leave Benghazi and then you have ... nothing but gangs and youths with weapons," he added. "The way from Benghazi is extremely dangerous," he said.Libyan guards have withdrawn from their side of the border and Egypt's new military rulers -- who took power following the overthrow of President Hosni Mubarak on Feb.11 -- said the main crossing would be kept open round-the-clock to allow the sick and wounded to enter.
