Thousands of Gaza residents broke into warehouses and distribution centres of the United Nations Palestinian refugee agency (UNRWA) grabbing flour and “basic survival items”, the organisation said on Sunday.

“This is a worrying sign that civil order is starting to break down after three weeks of war and a tight siege on Gaza,” the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) said in a statement.

One of the warehouses, located in Deir al-Balah, is where UNRWA stores supplies from the humanitarian convoys crossing into Gaza from Egypt.
