At least five people have died in a Nato air strike that hit a house in the Libyan capital Tripoli, Libyan government officials say. A three-storey house was badly damaged at the scene of the alleged air raid in the city's Souk al-Juma residential district. Correspondents were later shown five bodies at a Tripoli hospital. Nato is investigating the incident. It has admitted hitting mistaken targets in the past. "Nato was operating in Tripoli last night," Nato spokesman Wing Cdr Mike Bracken told the BBC. "Those areas that might have been claimed to be residential by the Gaddafi regime in the past have turned out to be being used as C2 nodes [command and control centres]." "We've worked very hard throughout the whole of this campaign to avoid the loss of civilian life by ensuring precision munitions are used. Please look at our record over the last few months regarding this." Family killed? If proved to be a Nato strike, the incident will raise more questions about the alliance's mission in Libya, says the BBC's Jeremy Bowen in Tripoli. Our correspondent was taken by Libyan government officials to the site and later to a Tripoli hospital where he was shown the bodies of a dead woman, a dead man and a dead baby. The officials said they were members of a family killed in the alleged Nato air strike. Our correspondent was also shown the body of another man and a dead baby. He saw two of the bodies earlier at Souk al-Juma; one was being pulled from the rubble and another was being placed in an ambulance. Libyan officials say Sunday's attack, in one of the city's poorer neighbourhoods, happened shortly after midnight. Scores of men were working alongside the emergency services, pulling at sections of rubble and looking for bodies. Locals said an entire family had been killed, though our correspondent was unable to immediately verify this claim. 'Seed of hatred' The level of damage, he adds, looked like the aftermath of an air strike, with concrete floors blown out onto the street - the incident did not look like a government stunt. The site is about one mile from a military airfield which has been frequently targeted by Nato. Libyan government spokesman Moussa Ibrahim said: "Nato is planting the seed of hatred in the hearts of Libyan people for years to come. They won't allow foreign armies to decide their future." Deputy Foreign Minister Khaled Kaim told reporters at the site that this represented "intentional and deliberate targeting of civilian houses". The incident occurred just over 24 hours after the country's prime minister accused Nato of specifically targeting civilians in its campaign. Libyan rebels hold a third of the country in the east and pockets in the west, including Misrata, although Tripoli remains under government control. Nato has flown more than 10,000 sorties since operations began, including almost 4,000 strike attacks against government targets across Libya. Source: BBC
