Confirmation: Hamas did it to themselves. JPost:

Hamas’s military wing, Izzadin Kassam, said Friday that the previous day’s deadly blast in the northern Gaza town of Beit Lahiya was caused by an accident as operatives were “preparing for a special jihad operation.” Eight people, including an infant girl, were killed in the powerful explosion, which flattened the home of a Hamas operative. Hamas initially blamed Israel for the blast, but the IDF immediately said that it was not involved, pointing to a possible “work accident,” most likely caused by terrorists’ faulty handling of explosives.

A “work accident?” Too bad the terrorists don’t have AFLAC.
