(CNN) - The situation in Libya "is still very fluid," U.S. President Barack Obama said Monday.
"There remains a degree of uncertainty and there are still regime elements who pose a threat," he said in taped remarks. "But this much is clear. The Gadhafi regime is coming to an end and the future of Libya is in the hands of its people."
Obama stressed that the battle "was not over yet." He called on Moammar Gadhafi to surrender and tell his supporters to lay down their arms.
"Although it's clear that Gadhafi's rule is over, he still has the opportunity to reduce further bloodshed," he said.
