As coalition troops tighten their control over Baghdad, U.S. forces on Wednesday focused their attention on key targets in northern Iraq, including Tikrit, Iraqi leader Saddam Hussein's hometown, and the northern city of Mosul.

As Iraqis hail the fall of Saddam's Baghdad, experts look ahead to the Bush administration's plans for a postwar Iraq, the feat of internationalizing the country's transition, and the difficulty of creating a democracy in an undemocratic region.

Defense Secretary Donald Rumsfeld and Joint Chiefs Chairman Gen. Richard Myers praised the fall of Baghdad, but said danger in Iraq remains. They detailed the military's goals and spoke about Iraq's humanitarian situation at the Pentagon.

As military efforts in Baghdad continue, conditions are worsening for aid agencies such as the International Committee of the Red Cross and Doctors Without Borders, both of whom suspended operations in Baghdad following the death of a Red Cross employee.
