Jordan, Morocco, Qatar and the United Arab Emirates are the Arab nations attending Saturday's summit in Paris on action in Libya, a diplomat told Agence France Presse.

Iraqi Foreign Minister Hoshyar Zebari will also attend in his capacity as current head of the Arab League. The League's Secretary General Amr Moussa will also take part.

French President Nicolas Sarkozy, British Prime Minister David Cameron and U.S. Secretary of State Hillary Clinton held talks ahead of Saturday's summit on action in Libya, sources said.

They represent the countries at the forefront of calls for military action in Libya to prevent Moammar Gadhafi's forces attacking rebels, sanctioned by a U.N. Security Council resolution on Thursday.

Libyan leader Moammar Gadhafi has sent urgent messages to French President Nicolas Sarkozy and British Prime Minister David Cameron telling them they "will regret" interfering in the country's affairs, a spokesman said Saturday.

"If you intervene in our country you will regret it," the spokesman quoted him as telling them, adding that Gadhafi had also sent messages to U.S. President Barack Obama and U.N. chief Ban Ki-moon.

Fighting raged around Libya's rebel stronghold of Benghazi Saturday, with air strikes, shelling and anti-aircraft fire rocking the Mediterranean city as a war plane went down in flames.

Hundreds were seen fleeing the city eastwards amid unconfirmed reports that forces loyal to Libyan strongman Moammar Gadhafi had entered the western suburbs of the city of more than one million people.

Al-Qassam Brigades fighters fired dozens of shells into Israel Saturday, reportedly wounding at least two people, while Palestinians said five had been hurt in an Israeli air strike.

The armed wing of the radical Hamas movement governing the Palestinian territory said it had mounted the attack, which Israel said saw 49 mortar bombs fall on Israeli communities near the border with the Gaza Strip.

Police shot and wounded an anti-regime protester in the Yemeni city of Aden on Saturday as they tried to disperse demonstrators, witnesses said.

Three other demonstrators were wounded in clashes with the security forces, they said, as opposition activists continue to demand the resignation of embattled President Ali Abdullah Saleh.

A Facebook page, one of the motors behind an unprecedented string of protests in Syria, called for a Saturday rally in the city of Homs, north of Damascus.

The Facebook group -- which has called several days of protest with different degrees of success -- disclosed the location of the demonstration in advance, a bold gesture in a country infamous for its tight grip on security.

Fighting raged around Libya's rebel stronghold of Benghazi Saturday ahead of a key meeting in Paris to discuss international military action against Moammar Gadhafi's government forces.

The southern edge of the city suffered at least two air strikes and sustained shelling, sending thick smoke into the sky, and a warplane crashed in flames, an Agence France Presse reporter said.

Arab League chief Amr Moussa hailed a huge turnout for a landmark referendum in Egypt on Saturday as voters seized their first taste of democracy after the ouster of veteran president Hosni Mubarak.

Queues had formed outside voting centers even before polls opened at 8:00 am (0600 GMT), something unheard of in the Mubarak-era when turnout for elections was always tiny as voters assumed their ballots would make no difference.

U.S. President Barack Obama Friday threatened defiant Libyan leader Moammar Gadhafi with military action unless he met specific, "non-negotiable" demands for a ceasefire, a halt to attacks on civilians and a retreat from rebel strongholds.

Obama said the world could not stand by because, if left unchecked, Gadhafi would commit atrocities in which thousands could die, adding that the Libyan strongman had been given "ample warning" to change his behavior.
