(IsraelNN.com) A Gaza-based organization has expressed "deep concern" at the recurrence of "internal explosions" caused by the manufacture and storing of weapons in civilian areas.

The PCHR (Palestinian Center for Human Rights) released its statement after Thursday's tremendous explosion in a large house in northern Gaza, which killed an infant, a 16-year-old and six terrorists.  Forty people were wounded in the blast.

PCHR announced it is "deeply concerned about the recurrence of internal explosions as a result of weapons being manufactured, and stored, in areas populated by civilians. These actions are threatening the lives and property of Palestinian civilians."

PCHR further called upon "Palestinian resistance groups to take immediate measures and effective steps to ensure the non-recurrence of such explosions." Such measures were not spelled out, but the PCHR warned "of the dangers caused by continued manufacturing or storage of explosive devices by Palestinian resistance groups in civilian-populated areas, which threaten the lives of Palestinian civilians and violate international humanitarian law." 

The PCHR announced that its investigation had found that early Thursday afternoon, June 12, "a huge explosion occurred in a 400-square-meter house belonging to Abdul Azim Khaled Hammouda... The house was completely destroyed and dozens of neighboring houses were also damaged, five of them seriously.  Ambulances and civil defense crews rushed to the area, and removed victims' bodies from beneath the ruins of the destroyed house and neighbouring houses."

Terrorists Killed "Preparing for Jihad Mission"
The Izzaddin al-Kassam Brigades, the official armed wing of Hamas, stated in a press release the next day that six of its members were killed "while they were in the final stage of preparation for a special Jihad mission."  The six would-be murderers ranged in age from 20 to 32.  Blame was originally apportioned to Israel for attacking the house.

The Associated Press reported that "dozens of Palestinian militants" have been killed in accidents while "mishandling explosives. "
