NATO will convene an emergency meeting on Friday to discuss unfolding situations in Libya.

Secretary-General Anders Fogh Rasmussen, who is in Hungary to attend an informal meeting of EU defense ministers, called for an emergency session on Libya.

"The situation in Libya is of great concern. NATO can act as an enabler and coordinator if and when member states will take action," he said in Godollo, a town near Budapest.

But any intervention must be based on a United Nations mandate, he added.

The UN Security Council will also meet Friday in New York to mull possible actions against Libyan leader Moammar Gaddafi's regime.

Many nations continued their efforts on Friday to evacuate their citizens from the North African country, as Gaddafi loyalties engaged in fierce fight with opposition forces.
