US Secretary of State Hillary Clinton arrived in Turkey early Saturday for talks on the worsening crisis in Syria. Clinton is set to meet with Turkish leaders as well as Syrian opposition activists to discuss preparations for a transition of power in Syria if the government of President Bashar al-Assad falls. US officials said the secretary of state wants to understand Turkey's position and its concerns as conditions in Syria deteriorate. She is also expected to announce more humanitarian aid for those fleeing the violence. The United Nations said there has been a surge in the number of civilians fleeing violence in Syria, especially from the northern city of Aleppo. Turkey, like all of Syria's neighbors, is dealing with a growing humanitarian crisis as thousands of refugees flood across the border. Turkey is currently supporting more than 50,000 Syrian refugees with more arriving every day.
