Israel’s renewed offensive in Gaza has reportedly left at least 322 children dead and 609 wounded in the Palestinian territory in the past 10 days, Unicef said, according to AFP.

The figures include children who were reportedly killed or wounded when the surgical department of Al Nasser Hospital, in southern Gaza, was hit in an attack on March 23, the UN children’s agency said in a statement.

Unicef said most of these children were displaced, and sheltering in makeshift tents or damaged homes.

“The ceasefire in Gaza provided a desperately needed lifeline for Gaza’s children and hope for a path to recovery,” said Unicef Executive Director Catherine Russell.

“But children have again been plunged into a cycle of deadly violence and deprivation.”

Russell added: “All parties must adhere to their obligations under international humanitarian law to protect children.”
