Libya's ambassador to the United States, Ali Suleiman Aujali, called for Libyan leader Col. Muammar Qadhafi to step down and "leave our people alone." The United States needs "to raise their voice very strongly," the ambassador told ABC's Good Morning America. "This regime is shaking, and this is the time to get rid of it." Aujali said there have been brutal killings and violence since the antigovernment protests broke out in the North African nation last week. "Please help the Libyan people," he said. "They are burning." However, Qadhafi, who has been in power since 1969, has refused to step down. In his first major speech since the protests began, Qadhafi said, "It is not possible that I leave this place," and also said that he "will be a martyr in the end."
