Moammar Gadhafi's youngest son, Khamis, has been killed in a clash with rebel fighters in southern Libya, Al-Arabiya television quoted the rebels as saying on Monday.

Meanwhile, Gadhafi's wife and three children fled to Algeria on Monday as rebels closed in on his hometown of Sirte and said the strongman still posed a danger to Libya and the world.

The Loyalty to the Resistance bloc condemned on Monday the statements that were recently issued against the Lebanese army, warning that such attacks may serve the goals of Lebanon’s enemies.

It said in a statement after its weekly meeting headed by MP Mohammed Raad: “The attack is part of a suspicious agenda that has been, for a while, seeking to bind Lebanon’s equation of strength.”

Algerian Foreign Minister Mourad Medelci has held talks with senior Libyan rebel figure Mahmud Jibril on the sidelines of an Arab League meeting in Cairo, an Algerian government spokesman said Monday.

"Mr. Medelci met with Mahmud Jibril on the sidelines of the Arab League meeting in Cairo which has just taken place," foreign ministry spokesman Amar Belani said in a statement, adding that the meeting had been initiated by Jibril who is the number two in the rebels' National Transitional Council.

Libyan rebels prepared Monday to launch an assault to capture strongman Moammar Gadhafi's hometown of Sirte and win full control of Libya, while scrambling to get war-ravaged Tripoli back on its feet.

Sirte is the elusive Gadhafi's last bastion after rebels smashed his forces in Tripoli and seized his Bab al-Aziziya headquarters.

Libyan rebels said Sunday that one of Moammar Gadhafi’s son, Khamis, whose death has been announced several times since the conflict erupted, may have been killed a day ago in a clash with rebels.

On Saturday, a brigade of rebel fighters in the city of Tarhuna, 80 kilometers southeast of the capital Tripoli "intercepted a military convoy which had several brand new Mercedes vehicles", rebel military spokesman Ahmed Omar Bani told reporters in Benghazi.

Libyan rebels closed in on Moammar Gadhafi’s hometown of Sirte from both east and west Sunday, a senior military commander said, as the insurgents scrambled to restore essential services to Tripoli.

Fierce fighting was also raging in the west of the country as rebels trying to take full control of the region said they had fallen into an ambush in a town southwest of Zuwarah.

Iran "discreetly" provided humanitarian aid to Libyan rebels before the fall of Tripoli, Jam-e-Jam newspaper quoted Foreign Minister Ali Akbar Salehi on Sunday as saying.

"We were in touch with many of the rebel groups in Libya before the fall of (Moammar) Gadhafi, and discreetly dispatched three or four food and medical consignments to Benghazi," Salehi told the daily.

The homes of fallen Libyan strongman Moammar Gadhafi's children tell of the siblings' privileged and security-conscious lives but do not display the extravagance of ex-Iraqi dictator Saddam Hussein's sons.

"These are the homes of Gadhafi's sons," said one rebel who gave his name as Marwan, pointing to three seafront houses in the district of Regatta on the outskirts of the capital.

A top Libyan rebel commander said on Sunday insurgent forces were 30 kilometers (18 miles) west of Moammar Gadhafi's hometown bastion of Sirte and 100 kilometers away in the east after seizing Bin Jawad.

"We took Bin Jawad today (Sunday)" on the eastern front, and "the rebel fighters from Misrata are 30 kilometers from Sirte" in the west, Mohammed al-Fortiya, the rebel commander in Misrata, told AFP.

Libyan rebels on Friday took control of the Ras Jdir post on the border with Tunisia, and raised the flag of the rebellion, a Tunisian government source told Agence France Presse.

"More than 100 Libyan rebels arrived Friday at Ras Jdir," the source said.
