The UN Relief and Works Agency has warned of a severe humanitarian crisis as people in the Gaza Strip run out of food and medicine.
The UNRWA says the number of displaced Palestinians seeking shelter in Gaza now exceeds 50,000 in 44 UN schools.
The agency says it is concerned that a more intensive military operation will mean these numbers rise even higher, imposing an additional burden on people who are already vulnerable.
The UNRWA is especially concerned by the impact this is having on the 1.2 million refugees it serves, the majority of whom were already reliant on food handouts and other assistance from the organisation.
So, what does it take to face this humanitarian crisis?
