DEIR AL-BALAH, Gaza Strip (AP) — Israeli strikes on northern Gaza have killed at least 22 people, Palestinian medical officials said. The Gaza Health Ministry’s emergency service said that 11 women and two children were among those killed in the strikes late Saturday on several homes and buildings in the northern town of Beit Lahiya. Israel has been waging a massive air and ground offensive in northern Gaza for the last three weeks, after saying that Hamas militants had regrouped there.
