Key developments Friday in the war in Iraq:

• U.S.-led forces expanded their control over Iraq as Mosul, largest city in the north, fell without a fight. But looting erupted and U.S. special forces were called in.
• Saddam Hussein’s hometown of Tikrit is the last major holdout of his regime, but no major troops units remain in the country, the Pentagon said.
• President Bush, declining to declare victory, said that he didn’t know whether Saddam Hussein was dead or alive but “I know he’s no longer in power.”
• Gen. Tommy Franks instructs U.S. troops to ensure that public services and religious institutions continue to operate in the Iraqi capital.
• Kurdish fighters will leave oil-rich Kirkuk when enough American troops arrive to take over, said a senior Kurdish leader.
• Defense Secretary Donald Rumsfeld characterized looting in Iraq as a period of “untidiness” and suggested it was only a transitional phase on the way to freedom.
• Since reaching Baghdad, U.S. Marines have been doing their own kind of looting — grabbing Iraqi pistols, rifles, uniforms and pictures of Saddam Hussein. Now they’ve been ordered to dump what they took or lose their rank.
• President Vladimir Putin said he welcomed the fall of Saddam Hussein but called the U.S.-led war in Iraq illegitimate and a threat to international law.
• The International Committee of the Red Cross said it didn’t know the whereabouts of the seven U.S. prisoners of war or who in Iraq is responsible for them.
• U.S. soldiers found the personal weapons cache of Saddam Hussein’s son Odai, including boxes of assault rifles and dozens of ceremonial firearms in an abandoned house in Baghdad.
