The UN’s Relief and Works Agency, the main provider of aid in Gaza, has warned that its operations there will have to stop unless fuel supplies are allowed in, the Guardian reports. The paper says fuel is normally used to pump and desalinate water, meaning that without it people will be forced to drink dirty water, and that it is also needed to run hospital generators. It also quotes Oxfam saying that Gaza is currently receiving just 2% of its usual supply of food.
