Report questioned -- Saif al-Arab Gaddafi, the youngest son of the Libyan leader, and three of his grandchildren have been killed
Ibrahim had earlier taken journalists to the remnants of a house in Tripoli, which Libyan officials said had been hit by at least three missiles. Given the level of destruction, it is unclear that anyone could have survived.
Benghazi rebels, who control a vast swathe of the east of the country, say they cannot trust Gaddafi.
Al Jazeera's Sue Turton, reporting from Benghazi, said there were "an awful lot" of suggestions in Libya that the news of the deaths could be fabricated. "One of the main spokesmen for the Transitional National Council, Abdul Hafez Goga, is saying he thinks it could all be fabrication, that it may well be Gaddafi is trying to garner some sympathy," she said. "Back in 1986, Gaddafi once claimed that Ronald Reagan, then US president, had launched a strike on his compound in Tripoli and killed his daughter. Many journalists since then dug around and found out that the actual child that had died had nothing to do with Gaddafi, that he sort of adopted her posthumously." Three loud explosions were heard in Tripoli on Saturday evening as jets flew overhead. Volleys of anti-aircraft fire rang out following the first two strikes, which were followed by a third. There was no immediate NATO reaction, nor was any independent confirmation of the deaths possible. US White House press secretary Jay Carney said the White House was aware of Libyan media reports Gaddafi's son had been killed and was monitoring the situation, while White House spokesman Shin Inouye declined to comment on the incident, referring questions to NATO. Rifle fire and car horns rang out in Benghazi as news of the attack spread.
Cars whizzed by the sea front beeping their horns and shouting "God is greatest" as the night sky was lit up by red tracer fire.
Saif al-Arab Gaddafi, the youngest son of the Libyan leader, and three of his grandchildren have been killed in a NATO air strike, a Libyan government spokesman said. Gaddafi and his wife were in the Tripoli house of his 29-year-old son, Saif al-Arab Gaddafi, when it was hit by at least one missile fired by a NATO warplane late on Saturday, according to Libyan government spokesman Moussa Ibrahim."The house of Mr Saif al-Arab Gaddafi was attacked tonight with full power. The leader with his wife was there in the house with other friends and relatives. "The leader himself is in good health, he wasn't harmed," the spokesman said, adding that Muammar Gaddafi's wife was also unharmed but other people in the house were injured. "This was a direct operation to assassinate the leader of this country. This is not permitted by international law. It is not permitted by any moral code or principle. "What we have now is the law of the jungle," Ibrahim told a news conference. "We think now it is clear to everyone that what is happening in Libya has nothing to do with the protection of civilians." The 29-year-old Saif al-Arab Gaddafi is the most unknown of the Libyan leader's children, Al Jazeera's Anita McNaught, reporting from Libya, said. "He's one of the low-profile of his children and has been largely invisible since the conflict began", she said. "He hasn't been visible in any significant form. He hasn't appeared on TV or made any speeches, he hasn't been on any crowd-rallying marches." Ibrahim said Saif al-Arab was a civilian and a student who had studied in Germany.
