In a video that has gone viral, a man in Gaza accuses the Israeli army of dropping booby-trapped cans of food into the besieged Palestinian enclave, claiming that the Israeli army left them behind to try and trick Gazans into trying to eat them. These cans do contain fuses used to set off mines, but the labels clearly state that they contain "fuses". They will not, however, explode when they are opened, says an expert.
