Israel killed at least 11 people across the Gaza Strip late Saturday, including three children and their parents, local health officials said, despite a cease-fire that has failed to end the violence.

A family of five, three children and their parents, were killed when an Israeli strike hit a residential apartment in northwest Gaza City, according to the territory's civil defense agency.

"The family's only surviving member is one child, who was not inside the house at the time of the strike," Mahmoud Bassal, spokesman for the agency, told AFP.

Gaza's al-Shifa hospital confirmed it had received the five bodies.

An Israeli military spokeswoman said a strike had been carried out in Gaza City Saturday targeting a Hamas member.
