BAGHDAD – The U.S. formally transferred control of the Green Zone to Iraqi authorities Thursday in a pair of ceremonies that also handed back Saddam Hussein's former palace. Iraq's prime minister said he will propose making Jan. 1 a holiday marking the restoration of sovereignty. Under the new security agreement between Washington and Baghdad to replace a U.N. mandate for foreign troops in Iraq, the Iraqi government also now has control of American troops' actions and of the country's airspace.
