A Palestinian man was killed and two others were injured when a car exploded in Gaza City’s Tal al-Hawa neighborhood before dawn Wednesday, an official said.Hamas admits that the dead man, 22-year old Ayman al-Sharafa was one of its members who was killed in an accidental explosion "during training."
So apparently Hamas transports explosive materials using ordinary cars traveling through residential neighborhoods.
I'm sure there is some ministry in Gaza where people can complain about that.
