A member of Hamas' military wing, the Al-Qassam Brigades, was killed on Wednesday night in an explosion in his Rafah home, southern Gaza.
The body of Ali Nayef, 20, from Yabna refugee camp was taken to Abu Yousef An-Najjar hospital, local witnesses told Ma'an.
The Al Qassam Brigades website calls it an "accident." Usually they say that it was in the course of a "jihad mission" but perhaps the neighbors would be upset if they admit that they are doing chemistry experiments in their own homes.
Despite the accidental nature of his timely demise, he is still regarded as a "martyr."
