Israeli army claims attack on Haniyeh's children in Gaza

At least three sons and three grandchildren of Hamas leader Ismail Haniyeh killed in Israeli air attack on Gaza refugee camp.

Haniyeh tells Al Jazeera that Palestinian leaders will not back down if their families are targeted by the Israeli army, and that the killings will not affect Hamas's demands in ceasefire talks.

Israeli army spokesperson Daniel Hagari says fighter jets attacked "three military operatives" in central Gaza, referring to a car carrying Haniyeh's children, who were killed earlier today.
