The French Defence Minister Gerard Longuet has suggested that a new UN Security Council resolution might be needed for NATO Allies to achieve their goal in Libya. Mr. Longuet said on French TV that a call from the British, French and American leaders for Col. Gaddafi to go exceeded the current UN resolution. A report from Paris says the UN resolution 1973, the basis for NATO action makes no mention of regime change in Libya but the main Powers now state quitely clearly that Col. Gaddafi must go. Mr. Longuet said it may be time soon for a new UN resolution. But in any case, the aim now is clear to persuade those still loyal to Col. Gaddafi that there can be no peace as long as he continues to rule and to induce them to come over to the rebels. The NATO Secretary General, Andres Fogh Rasmussen has said it is impossible to imagine that the threat to civilians in Libya will disappear while Col. Gaddafi is still in power. He said NATO was determined to continue its operation there for as long as civilians were threatened. Meanwhile, medical staff in the besieged Libyan city of Misrata say they are overwhelmed by the casualties inflicted by pro-Gaddafi forces. A report from Misrata says, in the overflowing wards of the main hospital, the intensive care unit is full of patients with multiple sharpnel injuries. Doctors said most of the patients had been wounded by heavy weapons and they said that 80 per cent of those killed or injured are civilians.
