Their sewers are erupting and killing their own children, but they’re still practicing to kill Israeli children: One killed in explosion at Hamas camp in Gaza.

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.
