President Barack Obama on Thursday said Libyan leader Muammar Qadhafi "has lost the legitimacy to lead, and he must leave." At a press conference Thursday, Obama urged the violence in Libya to stop and said his administration is putting in place "unprecedented sanctions to hold Qadhafi accountable." The president also pledged support for the tens of thousands of foreign workers, most of them Egyptian, fleeing Libya. The Obama administration has authorized military aircraft to return Egyptian workers home and has assigned the U.S. Agency for International Development (USAID) to charter additional civilian aircrafts to support evacuation efforts and has also authorized the organization to send assistance teams to the Libyan border. The president said the United States, along with the rest of the world, "continues to be outraged by the appalling violence against the Libyan people."
