Including both combatants and civilians, as reported by Israeli sources. This market will resolve after the war is over and official estimates are available. Close date may be extended.
Note: This market it only for Palestinian casualties, i.e. people from Gaza and potentially the West Bank (but only if the casualties are related to the war). This will not include any casualties from other parties that might join the war, nor of Israeli-Arabs, regardless of how they identify. This is done to clear up the market definitions and make it resolvable, not because of taking any stance as to people's identities.
