Israel has told everyone in the north of the Gaza Strip - about 1.1 million people - to relocate to the south of the territory within 24 hours.
The UN said this is not possible and asked Israel to withdraw the order, warning of "devastating humanitarian consequences".
The World Health Organization said Gaza's health authorities had told it that it would be impossible to evacuate vulnerable hospital patients.
Hamas, which controls the Gaza Strip, told civilians to ignore the evacuation order, describing it as "fake propaganda". However, many people have been leaving.
