Washington Post: "South Korea's Ban Ki-moon formally takes the reins of the United Nations Thursday as the institution grapples with internal reforms, volatility in the Middle East and international standoffs over the nuclear ambitions of North Korea and Iran.

Ban, who is being sworn-in before the General Assembly in a ceremony also honoring outgoing Secretary-General Kofi Annan, will not officially start his new job until Jan. 1, when he will become the eighth secretary-general of the 192-nation world body."
