Israeli strikes on the Gaza Strip overnight and into Tuesday killed at least 25 people, including eight children and five women, according to Palestinian medics.
A strike on a home in the central town of Deir al-Balah killed 11 people, including five children as young as two, according to the Al-Aqsa Martyrs Hospital, which received the bodies.
Another four people were killed in a separate strike that hit a house in Deir al-Balah, it said.
Another strike in the northern town of Beit Lahiya flattened a home and killed a family of seven, according to the Gaza Health Ministry.
A separate strike hit a group of people in an open area northwest of Gaza City, killing four people, including one who was planning to get married next week, the ministry said.
Israel says it only targets gunmen and blames Hamas for civilian deaths because it operates in densely populated areas.
