"The humanitarian catastrophe that we are witnessing in Gaza must end now," a joint statement from the three countries reads.

Israel will coordinate airdrops of aid into Gaza from foreign countries in the coming days, an Israeli security official confirmed to ABC News.

Britain, France and Germany are calling for an immediate end Israel's war in Gaza after dozens of people were killed over a 24-hour period in the territory.

The Israeli military announced on Sunday a daily pause of its operations in parts of Gaza and the establishment of new aid corridors, after months of international pressure over a worsening hunger crisis spreading in the Palestinian enclave.

The Israel Defense Forces (IDF) will implement a humanitarian pause in several population centers across the Gaza Strip beginning Sunday morning and lasting until the evening, according to senior Israeli officials.
