Government spokesman Mussa Ibrahim told reporters that at least three people were killed and 150 were injured in the air strikes, which he said targeted a deserted military barracks.An AFP journalist said the raids lasting more than half an hour when powerful blasts were heard in the sector around Gaddafi's Bab al-Aziziya residence.More than 15 strong blasts were heard in the neighbourhood, with the sound of warplanes roaring overhead. However, NATO rejected the claim that the strikes had targeted a barracks and said a vehicle storage facility had been struck. Meanwhile reports say, France and Britain are to deploy attack helicopters against Libya to increase the pressure to break the military stalemate.
