Sam Rose, director of planning at the UN agency for Palestinian refugees, says people in Gaza “are facing absolutely unimaginable conditions”, Al Jazeera reports.

They have been going through “12 months of war, repeated displacement, bombardment, loss of life, loss of property, deprivation and lack of food and water”, he told Al Jazeera from Khan Younis in southern Gaza.

“What we have seen over the past two weeks has taken it to another level in terms of the intensity of the bombardment and military operations,” Rose said.

“It is very difficult to get a precise read on what is going on due to the closure and the way the area is strangled, but every report we are getting suggests the situation up there for the approximately 175,000 people we estimate remaining is beyond catastrophic,” he added.
