GAZA, (Reuters) – Explosives detonated accidentally at a training camp used by Hamas’s armed wing in the southern Gaza Strip on Friday, killing one person and wounding at least 10 others, local residents said.

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.

The source identified the dead man as 21-year-old Kamel Musa, a Hamas militant.

An Israeli army spokeswoman confirmed that the Israeli military was not involved.
