Israeli strikes on the Gaza Strip have killed at least six people overnight, including two young children who died in the tent where their family was sheltering. Medical officials said Sunday that the strike in the Muwasi area, a sprawling tent camp housing hundreds of thousands of displaced people, also wounded the children’s mother and their sibling. A separate strike in the southern city of Rafah, on the border with Egypt, killed four men, according to hospital records. There was no immediate comment from the Israeli military. Israel says it only targets militants and tries to avoid harming civilians, but its daily strikes across Gaza often kill women and children.
