Gaza evacuations 'make UN's work impossible'

The UN has said its ability to function in Gaza is being crippled by a flurry of Israeli evacuation orders, forcing Palestinians into ever smaller and more remote areas, days before a critical effort to contain a polio outbreak.

Aid workers say that without a humanitarian pause, a vaccination drive due to begin this weekend could fail to reach enough children to stop the spread of the virus, which was detected there this month for the first time in 25 years.

A baby has already been partly paralysed by the disease, and health experts have warned it could spread rapidly given the terrible sanitation and overcrowding in camps for Gaza's exhausted, displaced population.

"One thing for sure is it's almost impossible to lead a polio vaccination campaign at scale in an active combat zone," said Jonathan Crickx, a spokesperson in the region for the UN child welfare agency, Unicef.

Talks are under way between aid agencies and the Israel Defense Forces (IDF) about the planned vaccination campaign. The IDF cooperated in the delivery of more than 25,000 vials of vaccine and refrigeration equipment through the Kerem Shalom crossing into Gaza on Sunday, but their commanders have yet to agree a pause in the bombing to allow the immunisation to go ahead safely and effectively.

Israeli forces have significantly stepped up their clearance of neighbourhoods, including camps for the displaced, in what they said was the pursuit of "terror operatives".
