The signatories are the foreign ministers of the UK and 27 other nations, including Australia, Canada, France, Italy, Japan, New Zealand and Switzerland.
The statement begins by declaring that "the war in Gaza must end now".
It then warns: "The suffering of civilians in Gaza has reached new depths. The Israeli government's aid delivery model is dangerous, fuels instability and deprives Gazans of human dignity.
"We condemn the drip feeding of aid and the inhumane killing of civilians, including children, seeking to meet their most basic needs of water and food. It is horrifying that over 800 Palestinians have been killed while seeking aid."
