Thirteen Palestinians were killed on Tuesday, including the sister of Hamas leader Ismail Haniyeh, when Israel bombed the family home in the Shati refugee camp west of Gaza City.

Civil Defence crews searched the ruins of the bombed house on Tuesday for survivors with one of the dead identified as Zuhur Abdul Salam Haniyeh, Ismail Haniyeh’s sister.

The Israeli army claimed it had “bombed two houses used by Hamas elements” without referring to Haniyeh’s family.

Another of Haniyeh’s sisters, Sabah, who holds Israeli citizenship and lives in Beersheba, was detained by Israel on 21 April but later released and placed under house arrest.
