1536: The Arab League's secretary general, Amr Moussa, has announced an emergency meeting of the grouping, saying that the current situation isn't what Arabs had envisaged. "What is happening in Libya differs from the aim of imposing a no-fly zone, and what we want is the protection of civilians and not the bombardment of more civilians," he said. Arab backing for a no-fly zone provided crucial underpinning for the passage of the U.N. Security Council resolution last week that paved the way for the Western intervention, the biggest against an Arab country since the 2003 invasion of Iraq. Withdrawal of that support would make it much harder to pursue what some defence analysts say could in any case be a difficult, open-ended campaign with an uncertain outcome. The U.S. Chairman of the Joint Chiefs of Staff, Admiral Mike Mullen, said the no-fly zone was effectively in place. But he told CBS the endgame of military action was "very uncertain" and acknowledged it could end in a stalemate with Gaddafi.
