However, the IDF explained “terrorists in Gaza tried to … prepare explosives to attack Israel. What terrorists in Gaza actually did [instead, was] cause an explosion in a civilian area inside Gaza.” Advertisement The Abu Ali Express blog reported that a Fatah-linked source said the sounds of the blast were due to the explosion of a rocket that was being stored at a house in the northeastern Gaza town of Beit Hanoun. The rocket that blew up was allegedly a âBader 3â and it was being stored in the home of Ahmad Nahatz al-Qafarna along with other munitions, according to blogger Abu Ali.
