NATO airstrikes kill Gaddafi's younger son

The house of Seif al-Arab Gaddafi, 29, "was attacked tonight with full power," government spokesman Moussa Ibrahim told a news conference announcing the deaths in the Saturday evening strikes.

The Libyan strongman and his wife were in the building that was hit, but were not harmed, Ibrahim said, though others present were killed or wounded in what he deemed "a direct operation to assassinate the leader of this country."

"The leader himself is in good health; he wasn't harmed. His wife is also in good health; she wasn't harmed, (but) other people were injured," he added.

Ibrahim later said intelligence on Gaddafi’s whereabouts appeared to have been "leaked."

"They knew about him being there, or expected him for some reason," the spokesman said.

NATO said it had staged airstrikes in Tripoli but did not confirm the Libyan claims. There was no immediate confirmation of the deaths either. At least three missiles had been heard exploding loudly over the capital earlier as jets flew overhead.

The transatlantic military alliance "continued its precision strikes against Gaddafi regime military installations in Tripoli overnight, including striking a known command and control building in the Bab al-Azizya neighbourhood shortly after 08:00pm Saturday evening," a statement said.

Automatic gunfire, apparently in mourning, echoed across the capital following the announcement, while state TV showed flag-waving demonstrators whom it said turned out to mourn Seif al-Arab's death.

Overjoyed rebels fired rockets, Kalashnikovs, TNT and 12.5 anti-aircraft machine guns for more than a half an hour, rocking the rebel capital of Benghazi with sustained gunfire and explosions to mark the moment.

"They are so happy that Gaddafi lost his son in an air strike that they are shooting in celebration," said Colonel Ahmed Omar Bani, military spokesman of the Libyan opposition Transitional National Council (TNC) headquartered in the eastern city.

Cars whizzed by the seafront beeping their horns as people shouted "God is greatest" below a night sky lit up by red tracer fire.

Ibrahim had earlier taken journalists to the remnants of a heavily damaged house in Tripoli, hinting but not explicitly indicating this was the one in which Kadhafi's son had died.

Long, twisted rods of reinforcing steel bars stuck out of large chunks of blasted concrete lay in and around the structure. In some areas, the roof had caved in completely and walls had collapsed. A thick layer of dark grey dust covered the grounds.

Given the level of destruction, it was unclear that anyone could have survived, raising the possibility that if Kadhafi was there, he had left beforehand.

NATO vowed to stage more strikes, though the commander of NATO's Operation Unified Protector stressed that "we do not target individuals."

"All NATO's targets are military in nature and have been clearly linked to the... regime's systematic attacks on the Libyan population and populated areas," added Lieutenant-General Charles Bouchard.

In a speech on state television Saturday, Gaddafi had said NATO "must abandon all hope of his departure."

"I have no official functions to give up: I will not leave my country and will fight to the death," he said.

But he added a conciliatory note: "We are ready to talk with France and the United States, but with no preconditions.

"We will not surrender, but I call on you to negotiate. If you want petrol, we will sign contracts with your companies -- it is not worth going to war over.

"Between Libyans, we can solve our problems without being attacked, so pull back your fleets and your planes," he told NATO.

His call was dismissed by the TNC, which has shaped itself into a parallel government in Benghazi, and by NATO.

"The time for compromise has passed," said TNC vice chairman Abdul Hafiz Ghoga.

"The people of Libya cannot possibly envisage or accept a future Libya in which Gaddafi’s regime plays any role."

In Brussels, a NATO official also rejected talks.
