The girls were identified by Palestinian medical sources as Ayah, Eiman, Ikram, Tahrir and Samar Ba'lousha. They were killed after an Israeli airstrike hit their family home near the Imad Aqil Mosque in Jabalia, which was subsequently destroyed.
Dozens of houses in Jabalia have been destroyed and several victims remain under debris since shortly before midnight on Saturday; Palestinian rescue workers are still trying to get them out.
Israeli air raids also killed three children from the Al-Absi family in the Tal Al-Hawa neighborhood of Gaza City, as well as a brother and his sister from the Kishku family in the Zaytoun neighborhood of Gaza City.
Three other Palestinians from the Ar-Rayyis family were killed in front of their own shop on the same street. A father and his son were later killed in the same area.
Seeking shelter for Gazan children became impossible as the strip lacks fortified places to protect Palestinians from air raids, unlike nearby Israeli towns.
Since Saturday, two Israelis have been killed and about 20 others are injured from projectile attacks.
Gaza is the most densely populated place on the planet, with nearly 1.5 million Palestinians contained to a 20 square meter strip on the Mediterranean coast. Palestinians living in Gaza have been without food, electricity or water in their homes for several weeks.
