Moussa Koussa, the former Libyan foreign minister who resigned his position and fled to the United Kingdom, has not been offered immunity from prosecution and is "voluntarily talking" to authorities, British Foreign Minister William Hague said on Thursday.

Koussa was staying in a safe and secure place and engaged in ongoing discussions with British diplomats, including some who worked at the now-shuttered embassy in Libya, Hague said.

"His resignation shows that [Muammar] Gaddafi's regime ... is fragmented, under pressure and crumbling from within," he said.

Hague said Koussa had been his contact with the regime in recent weeks and that he had spoken with him several times.

"One thing I gathered between the lines of my telephone calls ... was that he was very distressed and dissatisfied" by the regime's response to protests, Hague said.

Koussa's resignation deals a serious political blow to Gaddafi, Libya's leader for 41 years, even as the regime's troops beat back rebels in the east.

Fighting reached Brega, a village near a large petrochemical plant and oil exporting facility, on Thursday, after shelling from mortars and Grad rockets forced the disorganised opposition fighters to pull back from Ras Lanuf the day before.

A big catch

Despite the lost ground, the opposition could savour some positive developments on Thursday. Koussa, described as being a pillar of Gaddafi's regime and a member of his inner circle, became the highest-profile member of the government to resign.

Western media also reported that rebels had begun to receive support from British and American special forces troops.


Agents from the Central Intelligence Agency and Special Air Service have been working on the ground in Libya for weeks, helping to identify Gaddafi's troops for air strikes and meeting with rebel forces, reports said, possibly to pave the way for training and arms shipments.

Observers have speculated that Koussa, a longtime government employee who led the regime's intelligence agency for five years, could now be providing sensitive information as well. 

What arrangement he will make with the British government, considering his possible exposure to lawsuits or criminal prosecution for being involved with the regime, remains unclear, and Hague said Koussa has not been granted immunity from prosecution in the United Kingdom or elsewhere.

Members of the Libyan opposition abroad have alleged that Koussa had a role in the 1988 bombing of Pan Am Flight 103, which blew up over Lockerbie, Scotland, and killed 270 people.

Koussa was expelled from the United Kingdom, where he served as ambassador for less than a year, after saying the regime planned to kill two Libyan dissidents.

The international community, sensing a hard road ahead in their effort to assist the rebels' faltering military campaign against Gaddafi, want to see more leading regime figures abandon Libya.

"It is not through actions of war that we can make Gaddafi leave, but rather through strong international pressure to encourage defections by people close to him," Italian foreign minister Franco Frattini told Canale 5 television.

Hague said the British government encouraged others around Gaddafi to abandon him and "embrace a better future for Libya."

Many other Libyan government figures have resigned since the uprising against Gaddafi began on February 15 - interior minister Abdel Fattah Younis and justice minister Mustafa Mohamed al-Jalil have both left, as have numerous ambassadors around the world.
