Ali Aujali, Libya's ambassador to the United States, has said that he supports the interim government being formed in Benghazi by the country's former minister of justice.
Aujali said on Saturday the caretaker administration, which announced it would lead the country for three months to prepare for elections, was "the government for the whole of Libya".
"We want to support this government as the caretaker government until the liberation of all of Libya, which I hope will happen very soon," he said.
Libya's deputy UN ambassador, Ibrahim Dabbashi, also said on Saturday that his delegation supported "in principle" Abud Ajleil's caretaker government.
"In principle we support this government," Dabbashi, one of the first Libyan diplomats to denounce Gaddafi, told Reuters. "We are seeking more information about it, but yes, I think we support it."
Former Libyan justice minister Mustafa Mohamed Abdel Jalil - who resigned from Gaddafi's cabinet on Monday in protest at the killing of protesters - earlier told Al Jazeera he had led the formation of an interim government based in Benghazi, Libya's second city, in the eastern part of the country now largely free of Gaddafi's control.
He said the transitional government "has military and civilian personalities".
"It will lead for no more than three months - and then there will be fair elections and the people will choose their leader," he said.
Aujali, a veteran Libyan diplomat, praised Abdel Jalil.
"He is a very honest man. He was in charge of the justice issue in the eastern part of Libya when the regime asked him to hang an innocent Libyan citizen and he refused," Aujali said.
"I am sure he will gain support of all Libyans and of the international community," he added.
