Twenty-eight countries, including the UK, Canada, Japan and more than a dozen EU nations, have condemned the “drip feeding of aid” and “inhumane killing of civilians” in Gaza, as they demanded an immediate end to Israel’s war with Hamas in the shattered Palestinian enclave.

In one of the largest co-ordinated denunciations of Israel’s actions in Gaza, the countries on Monday warned that the suffering of Gazan civilians had reached “new depths” and branded a controversial, privately run aid distribution scheme introduced by Israel in the enclave as “dangerous”.

They also lambasted the repeated killings of Palestinians — including children — trying to collect aid, a day after Hamas accused Israeli forces of being responsible for the deaths of more than 60 people as they waited for a food convoy in north Gaza.
