US sends 'time to go' message to Gaddafi

US official says weekend meeting with envoys from Tripoli was to reaffirm Washington's call for Libyan leader to quit. US officials have met with representatives of Muammar Gaddafi to deliver a message that the embattled Libyan leader must go, a state department spokesperson said. The rare meeting between US diplomats and Gaddafi envoys on Saturday was held "to deliver a clear and firm message that the only way to move forward is for Gaddafi to step down," the official said on Tuesday. "This was not a negotiation. It was the delivery of a message," the official said in a statement issued in New Delhi, where Hillary Clinton, the US secretary of state, is on an official visit.
