US President George W Bush and the British Prime Minister, Tony Blair, have been meeting at Camp David for a summit on the war in Iraq.
President Bush said that US-led forces in Iraq 'are advancing day by day, in steady progress against the enemy'.
Brushing aside a question about whether the conflict could last months, Mr Bush said the war would last however long it took to win.
Tony Blair said the military operations had achieved a massive amount in the week since they started and he promised to achieve the aim of liberating the people of Iraq.
They both called on the United Nations to immediately resume the oil-for-food programme in Iraq.
Mr Bush said this urgent humanitarian issue must not be politicised and the security council should give Secretary-General Kofi Annan the authority to start getting food supplies to those most in need of assistance.
Negroponte walks out of UNSC meeting
However, tensions in the UN Security Council escalated this evening with the US ambassador walking out of a meeting even as members appeared close to revamping the UN oil-for-food programme.
John Negroponte left the council chamber as Iraq's UN Ambassador Mohammed Aldouri accused the United States of conducting a war to wipe out the Iraqi people.
Mr Aldouri was speaking at the end of a two-day council meeting on Iraq, called by the Arab League, at which dozens of non-council members denounced the invasion.
Fear of humanitarian crisis
The first aid shipment is expected to finally arrive in Iraq tomorrow amid mounting concern about a humanitarian crisis.
British soldiers succeeded in handing out emergency supplies in villages in the south of the country during the day.
But the numbers reached are dwarfed by the 1.5 million people trapped in Basra where the UN has warned of a crisis.
Water has been reconnected to just half of Iraq's second city which has endured days with none at all.
