A Nato air strike in the Libyan capital, Tripoli, has killed the son of Colonel Muammar Gaddafi, a government spokesman has said.
Colonel Gaddafi himself was in the large residential villa which was hit by the strike, the spokesman added, but was unharmed.
His son Saif al-Arab was said to be dead, as well as three grandchildren.
Nato has confirmed the air strike, without denying or confirming the reported deaths.
A Nato spokesman said the strike had hit a "known command-and-control building in the Bab al-Azizya neighbourhood".
"All Nato's targets are military in nature... We do not target individuals," said Lieutenant-General Charles Bouchard.
