President Barack Obama, addressing the U.N. General Assembly, singled out Syrian leader Bashar al-Assad, calling him a "tyrant" for dropping barrel bombs to "massacre innocent children." Obama's speech touched broadly on the U.N. helping nations work together in a time of threats from terrorism and economic contagion. "If we cannot work together more effectively, we will all suffer the consequences," Obama said.
United Nations Secretary-General Ban Ki-moon opened the 70th session of the General Assembly on Monday with an impassioned speech that covered at least a dozen serious problems the world faces.
