Gaza's civil defense agency said Saturday an overnight Israeli strike killed nine members of a Palestinian family including six children in the southern city of Rafah.

Five children aged one to seven and a 16-year-old girl were among the dead, along with two women and a man, according to the city's Al Najjar hospital, AFP reported. 

"Nine martyrs including six children were pulled out from the rubble after Israeli air forces struck a house of the Radwan family in Tal al-Sultan in Rafah," Gaza Civil Defense agency spokesman Mahmud Bassal said in a statement.
