Israeli strikes killed dozens of Palestinians in northern Gaza overnight, Palestinian health officials said on Wednesday, as Israel threatens to ramp up its military campaign in the enclave despite mounting international pressure.

The bodies of more than 50 people killed overnight had arrived at the Indonesian Hospital by noon on Wednesday, according to Marwan Sultan, director of the medical facility in the town of Beit Lahia. He said dozens more had been injured. Gaza’s health ministry also said that dozens of people were killed overnight, without specifying where.

Gaza health officials do not distinguish between combatants and civilians when reporting death tolls.
