The Libyan rebels council asked the Arab League for support as the new flag was raised on Saturday to replace Moamer Gaddafi's green flag at the organisation's headquarters in Cairo, DPA reported.
Mahmoud Jibril, seen as the foreign minister of the Transitional National Council, asked the 22-member organisation to pressure for unfreezing Libyan assets abroad.
"We need your support for lifting the sanctions at the Security Council," he told an emergency meeting for Arab foreign ministers. "Every minute the council fails to meet the people's needs could lead to a political vacuum."
The council seeks authorization from the United Nation's security council to unfreeze more assets abroad, after it enforced the sanctions earlier this year. On Thursday, the UN Sanctions Committee on Libya unfroze 1.5 billion dollars for humanitarian aid, but that amount is just a fraction of what has been frozen.
Jibril also proposed a dialogue for Arab youth, so that Arab leaders would learn more about the vision of new generations.
"We will request assistance from Arab states to ensure security, if we fail to do so," he said.
Earlier on Saturday, the council's leader Mustafa Abdul Jalil said that the council might ask police officers from Arab and Muslim countries to help with the security situation in Libya, adding that he did not want security forces from any other states.
On Thursday, the Arab League recognized the opposition Transitional National Council as the legitimate representative of the Libyan people and said the council would take the North African country's seat in the pan-Arab organization.
The organization suspended Libya from its sessions in February when troops of the embattled leader Moamer Gaddafi responded with bloody violence to anti-government protests.
Syrian Foreign Minister Walid al-Moallem did not attend the meeting, and the country was instead represented by the Syrian delegate to the organization Youssef al-Ahmed.
"The use of force and violence against Arab uprisings proved to be useless. Reform is the only option," Secretary General Nabil al-Arabi said at the meeting, which will also discuss the Syrian uprising that began since March, calling on President Bashar al-Assad to step down.
At least four Arab countries have recently recalled their ambassadors to Syria to protest against the deadly government crackdown on pro-democracy protesters.
Al-Arabi said that the Arab League had been under intense public pressure for its slow reactions to developments in the region, saying it needs to take clear stances.
