Panic at Jabalia Refugee Camp
The sound of an ambulance siren joins shouts from the crowd, as the vehicle is briefly seen entering the gates to the school.
The UN Relief and Works Agency (UNRWA) said it came “after two days of heavy bombardments in the area.”
“Earlier today, another shelter at Beach Refugee Camp was also damaged, with one child reportedly killed. Both locations are in the north of the Gaza Strip,” it added.
“Further south, two schools-turned-shelters in the Al Bureij Refugee Camp were hit. Two people were reportedly killed and 31 injured.”
