A top Libyan opposition figure arrived to Cairo on Tuesday on a private plane for talks with Egyptian officials, as fighting intensified on Libya's western border with Tunisia, DPA reported.
Ali Abdel-Aziz al-Issawi, who is representing the rebels' Interim Transitional National Council (ITNC), is scheduled to also meet with officials from the Arab League about possibly representing Libya ahead of a scheduled vote on Thursday for a new secretary-general for the league.
Libya's membership in the Arab League was suspended shortly after Moamer Gaddafi began using heavy force against protesters when the uprising began mid-February.
Meanwhile, days of battles between rebels and Gaddafi's forces for control of a key crossing at the Tunisia-Libya border has displaced more than 9,000 people in the last four days, according to relief agencies in the area.
The US government released data Tuesday saying that, in total, nearly 676,000 people have fled Libya since the uprising began.
Thousands have also been internally displaced, with up to 13,000 people fleeing the continued fighting in the northwestern city of Misurata.
Rebels in the besieged city said that corpses line the streets, with the opposition claiming over 1,000 people have been killed there since fighting began.
According to the Benghazi-based ITNC, around 12,000 people have been killed overall in Libya since the uprising began.
NATO said Monday they were able to destroy two mines around Misurata's port, which were left behind by Gaddafi's forces, but that they were working to locate a third mine that went missing at sea.
Misurata activists said Gaddafi's fourth eldest son, al-Mutasim, was recruiting youth in the western town of Zlitan, which is part of the district of Misurata, with many recruits dressed in civilian clothes and driving civilian cars.
Some were given gas masks, leading to speculation about their intentions and prompting rebel forces to boost check points against possible incursions.
