US President George W Bush has said that thanks to US-led forces in Iraq "the grip of terror around the throat of the Iraqi people is being loosened".
Bush said the Iraqi people would choose their new government
Speaking at a news conference with UK Prime Minister Tony Blair, Mr Bush said both countries were committed to freeing the people of Iraq, "however long it takes", and would stand by them in the challenges ahead.
In a passionate speech denouncing the Iraqi regime Mr Blair said two dead British soldiers shown on Arabic television on Wednesday had been "executed".
The US and UK would seek a series of United Nations resolutions on Iraq to secure the rapid delivery of humanitarian aid and the creation of an appropriate post-war administration, he said.
President Bush spoke of the urgent need to resume the UN's oil-for-food programme to help Iraqi civilians - but he warned that the aid effort should not be politicised.
In Iraq, US and UK forces have engaged in fierce fighting in at least three areas as they encounter stiffer resistance than had been expected.

After his summit with the US president at Camp David, Mr Blair is to travel to New York for a meeting with the UN Secretary General Kofi Annan.
In fresh military action US troops and members of Iraq's Fedayeen units have fought a major battle in the town of Samawah, the site of a crucial bridge on the way to Baghdad.
US forces have also bombed the town of Nasiriya after coming under fire overnight from defenders - as many as 30 US soldiers have been injured, some of them possibly by so-called friendly fire.
And UK tanks destroyed 14 Iraqi tanks and a number of armoured vehicles attempting to break out of the city of Basra.
Separately, hundreds of American troops have parachuted into northern Iraq in the first big US deployment north of Baghdad - what one unnamed US defence official called "the beginning of the northern front".
The Pentagon said the paratroops from the 173rd Airborne Brigade had taken control of a key airfield in Kurdish-controlled territory, about 50 kilometres (31 miles) north-east of the city of Irbil.
Also in northern Iraq, Kurdish militiamen have crossed the front-line into Iraqi government-controlled territory, seizing a hilltop position guarding the advance to the city of Kirkuk, after Iraqi forces withdrew.
In the fighting in the south, the Americans used heavy guns and tank shells as well as Apache helicopters to try to dislodge an estimated 1,500 Fedayeen fighters guarding a bridge across the Euphrates river.
The US needs to capture the town to secure its supply routes as its forces move north, according to the BBC's Gavin Hewitt, who is travelling with the troops.
