Lebanese Prime Minister Najib Mikati, center, leaves after he announced his resignation, at the government palace, in Beirut, Lebanon, Friday, March 22, 2013. Lebanon's prime minister has resigned due to an impasse over a new election law and the Cabinet's refusal to extend the tenure of the country's police chief. The Hezbollah-dominated Cabinet has also refused to extend the tenure of Maj. Gen. Ashraf Rifi, Lebanon's police chief, whom it considers a foe. (AP Photo/Hussein Malla), APTOPIX
