'It is impossible for 1.1 million people to leave their homes within 24 hours', says #BBC corr Tom Bateman in Jerusalem. 'It would involve 40,000 people per hour. On the ground convoys of the International Red Cross and United Nations humanitarian agency staff have been spotted travelling south from #Gaza City towards the southern part of territory, which may be in preparation of possible evacuation operation.
But it would bring chaos to try to carry it out on this scale within 24 hrs'

The militant group has long been criticised by the international community for using civilians as human shields - putting innocent people in danger to protect their fighters.
Hamas took power of the Gaza strip after it won the legislative elections in 2006, before reinforcing its power in Gaza the following year by ousting the rival Fatah movement of President Mahmoud Abbas.
#Israel 's #UN ambo defended the #evacuation order saying it was giving an early warning to the residents of #Gaza to "minimise harm to those not involved" in its military operation against #Hamas "For many years, the UN has turned a blind eye to the arming of Hamas, its use of the civilian population and civilian infrastructure in the Gaza Strip as a hiding place for its weapons and murder," Gilad Erdan said "It is better for the UN to focus now on returning the #hostages , condemning Hamas"
The Wadi Gaza is a river valley located around the centre of the #Gaza Strip, snaking across its entire width and ending in the Mediterranean Sea. It is known for its coastal wetlands and biodiversity. #Israel#hamas#WadiGaza
"You will be able to return to Gaza City only when another announcement permitting it is made," Israeli officials said in the statement to Gaza residents.
The #evacuation order is part of #Israel 's "humanitarian measures" in the #Gaza Strip, says #IDF spox Jonathan Conricus:"Civilians are not our enemy."
He said the military wants to minimise civilian casualties as it strikes targets in the Gaza Strip, and that it remains fully committed to the laws of international armed conflict.
The #Israeli military has told the #UN that everyone living north of Wadi Gaza should relocate to southern #Gaza in the next 24 hours, acc to a UN spox
The UN says this amounts to approx 1.1 million people - about half the population of the entire Gaza Strip. The affected area includes densely populated Gaza City.
The alert was given just before midnight local time #Israel#hamas
The #UN "strongly appeals for any such ( #evacuation ) order to be rescinded avoiding what could transform what is already a tragedy into a calamitous situation".
The order also includes all UN staff and those sheltered in UN facilities which includes schools, health centres, and clinics.
