Israeli air strikes in central Gaza killed at least 18 people, including children, a day after 33 were killed at a United Nations-run school sheltering displaced Palestinian families, health officials said.

Overnight strikes were recorded at the Nuseirat and Maghazi refugee camps and the towns of Deir al-Balah and Zawaiyda.
