In a briefing, Joyce Msuya warned that restoration of essential supplies and services is becoming increasingly critical.

The UN will continue working together with parties and States to seek pressing solutions to bring humanitarian aid to Gaza, Msuya added.

She also stressed the need to deliver these supplies and ensure humanitarian access across Gaza as more than 300 tons of vital supplies await passage at the Rafah border crossing between Egypt and Gaza.

At the same time, she warned of the overcrowding of the Palestinian population in the Gaza Strip, one of the most populated areas on the planet.

Civilians have nowhere to go, nowhere to escape from bombs and missiles, nowhere to find water or food, nowhere to escape from unfolding humanitarian catastrophe, she regretted.

UN Relief and Works Agency for Palestine Refugees (UNRWA), on the other hand, confirmed that at least six people were killed on Tuesday when one of its schools was attacked in the al-Maghazi displaced people camp.

UNRWA´s Commissioner Philippe Lazzarini described the incident as outrageous, proving once again a blatant disregard for civilians´ lives.

No place is safe in Gaza anymore, not even the Agency’s facilities, he said.

UNRWA stressed its deep concern over the lack of water, which can lead to dehydration and contamination-borne diseases.
