"The acute emergency needs in Iraq must be addressed quickly. In the first instance there is a need for food, water, shelter, healthcare and protection to the civilian population," Xinhua quoted Norwegian Foreign Minister Borge Brende as saying.
The recent attacks in Iraq have displaced 5,00,000 people from their homes. About 3,00,000 Iraqis have fled to the Kurdish areas in the country.
Preliminary estimates from the UN show that the number of displaced people could reach one million if the conflict spreads to other major cities, the Norwegian foreign ministry said in a statement.
"It is essential that the parties fully respect international humanitarian law on the protection of civilians and access for humanitarian aid," Brende said.
