Hundreds if not thousands of people have died since Libya's uprising began. More than 200,000 people have fled the country creating a humanitarian crisis across the border with Tunisia -- another North African country in turmoil after an uprising in January that ousted its longtime leader. President Obama said Monday that the U.S. and its NATO allies are still considering "potential military options" to stop the violence in Libya, warning those in Muammar al-Qaddafi's inner circle that they will be "held accountable" if they continue to stand by the leader's side.
