The humanitarian situation in Gaza has worsened again and is of serious concern, Britain, Canada, France and others said in a joint statement on Tuesday that also called on Israel to take urgent action.

The statement, published online by the British Foreign Office, said Israel should allow non-governmental organisations to work in Israel in a sustained and predictable way, and ensure the UN could continue its work in the Palestinian enclave.

“(We) express serious concerns about the renewed deterioration of the humanitarian situation in Gaza which remains catastrophic,” read the statement from the foreign ministers of Canada, Denmark, Finland, France, Iceland, Japan, Norway, Sweden, Switzerland and the United Kingdom.

It also said Israel should lift what it called “unreasonable restrictions” on certain imports including medical and shelter equipment, and open border crossings to increase the flow of humanitarian aid into Gaza.
