Israeli strikes overnight and into Tuesday have killed at least 60 people across the Gaza Strip, according to Palestinian health officials.
Israel has launched another major offensive in the territory in recent days, saying it aims to return dozens of hostages held by Hamas and destroy the militant group.
Two strikes in northern Gaza hit a family home and a school-turned-shelter, killing at least 22 people, more than half of them women and children, according to the Gaza Health Ministry.
A strike in the central city of Deir al-Balah killed 13 people, and another in the nearby built-up Nuseirat refugee camp killed 15, according to the Al-Aqsa Martyrs Hospital.
Two strikes in the southern city of Khan Younis killed 10 people, according to Nasser Hospital.
There was no immediate comment from the Israeli military, which says it only targets militants and blames Hamas for civilian deaths because the group operates in densely populated areas.
