Satu sumber Hamas di daerah itu mengatakan kepada Reuters, ledakan itu terjadi karena kecelakaan kerja yang membuat bom itu meledak secara tidak sengaja selama pelatihan di sebuah fasilitas di desa al-Qarara dekat kota miskin Khan Younis.
A Hamas source in the area told Reuters that the blast was the result of a work accident in which an explosive device went off accidentally during training at a facility in the village of al-Qarara near the impoverished town of Khan Younis.
