Twenty people were killed and dozens more injured in an attack “targeting” a school in northern Gaza, AFP reports citing the health ministry in the Palestinian territory.

“20 martyrs and dozens of wounded arrived at the Al-Shifa hospital in Gaza City after the direct targeting of a school turned into a makeshift camp for displaced people in the al-Saftawy area in northern Gaza,” the health ministry said in a statement.

“Several tank mortar shells fell into the school that was directly targeted,” it added.
