Israeli airstrikes have destroyed apartment blocks and killed dozens of people at a refugee camp in northern Gaza on the 25th day of a conflict that the United Nations said has become a graveyard for children.

At least six airstrikes hit residential areas in the Jabalia refugee camp on Gaza City's outskirts on Tuesday, killing more than 50 people and injuring around 150, Hamas officials said.
