BAGHDAD, Iraq - U.S. forces battled holdout fighters Thursday at a palace and a mosque in Baghdad; one Marine was killed and up to 20 wounded. In the north, America's Kurdish allies achieved a major breakthrough - entering the city of Kirkuk near some of Iraq's most productive oil fields.  President Bush, in a remarks televised throughout Iraq, told its citizens, "The long era of fear and cruelty is ending... the future of your country will soon belong to you."  Both skirmishes and widespread looting continued in Baghdad, a day after U.S. officials declared that Saddam Hussein's regime was no longer in control. U.S. Central Command said Marines engaged in "intense fighting" with pro-Saddam forces at the Imam Mosque, the Az Amihyah Palace and the house of a Baath party leader.

Thorp said he didn't know if Saddam was among those trying to organize the meeting, and he had no information on any regime leaders being captured or killed. 

That engagement aside, the largely one-sided battle for Baghdad appeared nearly over, and U.S. commanders were focusing on plans to oust pro-Saddam forces from their handful of remaining strongholds in the north - including Saddam's heavily defended hometown of Tikrit and the cities of Mosul and Kirkuk near the northern oil fields. 

A convoy of Kurdish fighters drove into an industrial neighborhood of Kirkuk on Thursday. There was shooting on the northwest edge of the city, but the extent of pro-Saddam resistance was unclear. 

After Wednesday's momentous celebrations, and after perhaps the quietest night since the war began, Baghdad residents were back out on the streets Thursday. 

Motorists flew white flags on their vehicles. Many people embarked on a new wave of looting, setting fires to some Interior Ministry buildings and making off with carpets, furniture, TVs and air conditioners from government-owned apartments, abandoned government offices and the police academy. 

Also looted was the German Embassy - representing a government that had emphatically opposed the U.S. decision to go to war. 

In Saddam City, a densely population Shiite Muslim district in Baghdad, some residents set up roadblocks, confiscated loot being brought back from the city in wheelbarrows and pushcarts, and sent the booty to a nearby mosque. 

Some U.S. units received word Thursday that they should try to stop the looting, but strategies for doing so remained incomplete. 

"There's civilian looting like crazy, all over the place," said Lance Cpl. Darren Pickard of Merced, Calif. "There just aren't enough of us to clear it out." 

One Baghdad man, Adel Naji al-Tamimi, 49, said had spent 17 years in prison for writing anti-Saddam articles. 

"He made himself a legend and a myth," al-Tamimi said. "His atrocities and oppression controlled our feelings and we're still afraid." 

In many parts of the country, civilians struggled with serious shortages of food, medicine and clean water. Several major international aid groups are demanding swift access to Iraqi civilians, without interference from U.S. or British troops. 

"We need the independence to move around and do our assessments and we need security," said Kathleen Hunt of Care International. "The images we see on television (of widespread looting) are not very encouraging in terms of lawlessness in certain parts of the country." 

Hoping to restore some degree of order to the southern city of Basra, British troops Thursday asked residents to turn in their guns - no questions asked. 

"If we want to give the new Iraq a chance, these weapons have to be taken out of circulation," said Capt. Cliff Dare of 3 Commando Brigade Engineer Group. 

Humanitarian assistance is expected to be high on the agenda of the U.S.-led interim administration that is expected to begin operating in Baghdad within the next week or two. Headed by retired U.S. Gen. Jay Garner, the team will coordinate relief programs, rebuild shattered infrastructure and start setting up a democratic government. 

Vestiges of the old government were vanishing rapidly. Statues and portraits of Saddam were toppled and defaced in Baghdad and other cities, while Iraqi diplomats at some embassies abroad shredded or burned documents. Iraq's U.N. ambassador, Mohammed Al-Douri, told reporters "the game is over, and I hope peace will prevail." 

Saddam's precise fate remained unknown. Hoping to resolve the mystery, U.S. special operations forces examined a site in a Baghdad residential neighborhood that was bombed Monday based on intelligence that Saddam and at least one of his sons were there. 

Though elated by the U.S.-led coalition's success, Defense Secretary Donald H. Rumsfeld said several missions remain to be accomplished before any victory declaration. Among them: securing the northern oil fields, determining what happened to Saddam and his sons, uncovering details of Saddam's weapons programs, and capturing or killing any terrorists still at large in Iraq. 

Across the Arab world, the fall of Baghdad - and the televised scenes of jubilation and looting - provoked shock, disbelief and bitterness. Some Arabs expressed hope that other oppressive regimes in the region would crumble; others were disappointed that Saddam's forces offered such weak resistance to America. 

After an anti-war march in Khartoum, Sudan, lawyer Ali al-Sayed said U.S. troops should not misinterpret the rejoicing in Baghdad as an invitation to stay. 

"Those people under oppression ... they will be happy to see someone removing a dictator and liberating them," al-Sayed said. "But the moment they feel free and liberated, they will not tolerate a foreign presence." 

The celebrations in Baghdad took place 21 days after U.S. forces started the war with an airstrike intended to kill Saddam. According to the Pentagon, 101 American troops died in the first three weeks of the war, 11 were missing and seven were listed as captured. The British said 30 of their troops were dead. There are no reliable estimates for Iraqi casualties; an Army spokesman said 7,300 prisoners had been taken.
