While in Gaza, Mr. McGoldrick visited the southern city of Rafah, located on the border with Egypt, and a crossing point for aid into the enclave.
Rafah normally has a population of around 280,000, which has swelled to an estimated 1.2 to 1.4 million as people fleeing fighting elsewhere pack into the city, setting up makeshift shelters and tents in the streets.
The squalid and unsanitary conditions have led to outbreaks of respiratory infections and hepatitis A, both of which had been eradicated in Gaza. Meningitis and other illnesses are also emerging.
The conflict in Gaza has displaced over 75 per cent of the population, with nearly 1.7 million people now living in UNRWA and public emergency shelters as well as informal sites.
