The UN Relief and Works Agency (UNRWA) reported that one of its schools being used as a shelter was demolished in strikes on Gaza’s Jabalia Refugee Camp, killing at least 20.
The UNRWA said it came "after two days of heavy strikes in the area."
It added that another shelter at Beach Refugee Camp was also damaged, with one child reportedly killed earlier on Thursday.
"Further south, two schools-turned-shelters in the Al Bureij Refugee Camp were hit. Two people were reportedly killed and 31 injured," UNRWA noted.
