Three sons and three grandchildren of Hamas leader Ismail Haniyeh have reportedly been killed in an Israeli airstrike on the Gaza Strip, according to local media reports.

A vehicle carrying the family members of Haniyeh, the head of Hamas’s political bureau, was reportedly targeted near Al Shati (“Beach Camp”), northwest of Gaza City.

A doctor at Al-Ahli Baptist Hospital in Gaza City told a CNN stringer that three dead adults and three dead children had been brought to the hospital.

Haniyeh has said he is aware of the reports that his family members had been killed. “I got word that the enemy struck a car with my sons. And they became martyrs,” he told Al Jazeera.

“They were martyred in Al Shati refugee camp,” Haniyeh continued.

The Hamas leader said that “targeting leaders’ houses and families” would only increase Hamas’ determination. “Whoever thinks that by targeting my kids during the negotiation talks and before a deal is agreed upon that it will force Hamas to back down on its demands, is delusional,” Haniyeh added.
