Gaddafi's warplanes bomb eastern Libyan town of Ras Launf

68-year-old Muammar Gaddafi's warplanes dropped missiles near rebel positions in the desert east of Ras Lanuf, reports reaching here said, adding there were no casualties or damage.

The Libyan ruler's supporters moved eastward in an effort to push the rebels back and recapture fallen towns, with reports emerging that they have taken the central town of Bin Jawad, according to Al-Jazeera.

There has also been fierce fighting in the eastern city of Misurata, located between the capital Tripoli and Gaddafi's hometown of Sirte.

As the uprising against Gaddafi's 41-year rule entered 22nd day, there were reports that the embattled leader had sent a representative to make a proposal to the opposition's so-called "National Council" based in Benghazi. It is said he wanted guarantees for his and his family's safety and immunity from prosecution.

But, Libyan state television denied the reports that Gaddafi tried to strike a deal with the rebels that would have seen him step down.

In Washington, US President Barack Obama tried to raise pressure on Gaddafi further by talking about "a range" of possible options, "including potential military options" against the embattled Libyan leader, even as Britain and France were drafting a UN resolution that would establish a no-fly zone.

Obama said the US would stand with the Libyan people as they face "unacceptable" violence.

"I want to send a very clear message to those who are around Colonel Gaddafi: It is their choice to make how they operate moving forward, and they will be held accountable for whatever violence continues to take place there," Obama said.

"In the meantime, we've got NATO, as we speak, consulting in Brussels around a wide range of potential options, including potential military options, in response to the violence that continues to take place inside of Libya," he added.

William Hague, the UK foreign secretary, said Britain is "working closely with partners on a contingency basis on elements of a resolution on a no-fly zone".

"There should be a demonstrable need that the whole world can see, there must be a clear legal basis for such a no-fly zone and there must be clear support from the region... as well as from the people of Libya themselves," he said.

The six US-allied Gulf Arab nations said yesterday they backed a UN-enforced no-fly zone over Libya to protect civilians.

They also condemned the killings by pro-government forces in Libya as "massacres".

Abdul Rahman Hamad al-Attiyah, the Secretary General of the Gulf Cooperation Council (GCC), said "the massacres committed by the regime" in Libya against its own citizens amount to "crimes against humanity".

Amid an exodus of foreign workers, the UN and the EU have announced that they were dispatching fact-finding missions to the north African country.

In an interview to television channel France 24, Gaddafi held the al-Qaeda responsible for plunging the country into chaos.

The Libyan leader said that his country was an important partner of the West in combating al-Qaeda and played a key role in checking sub-Saharan illegal migrants from moving into Europe.

According to UN estimates, over 1,000 people have been killed since Libya's uprising began on February 14.

More than 200,000 people have fled the country, most of them foreign workers. The exodus is creating a humanitarian crisis across the border with Tunisia.

The chief prosecutor of the International Criminal Court, Luis Moreno-Ocampo, has said that he will investigate war crimes allegedly committed by the Libyan leader and his loyalists.

American media reports said that US military had prepared a blue print of land, air and sea options in Libya in case Washington and its NATO allies decide to intervene there.

The options, they said, could range from arming the rebels to putting hi-tech aircraft in the international air space to jam Libyan military communication to sending teams of special forces to lead and guide the rebels.
