A school building where displaced Palestinian families were sheltering in Gaza City was reduced to rubble following an Israeli strike on Thursday, 3 April.
At least 27 people including women and children were killed in the strike, according to Gaza health authorities.
Israel's military said the Dar Al-Arqam school building in the Tuffah neighbourhood was used as a command and control centre by Hamas militants and accused the fighters of deliberately using civilian infrastructure as bases.
Hamas denies that it operates among civilians.
