London police have released photos of the fake suicide belts worn by the London Bridge terrorists ... which reportedly turned out to be water bottles wrapped in tape.
The belts were strapped to the 3 men as they mowed down pedestrians on the Bridge, then went to a nearby restaurant and stabbed numerous people.
All 3 were shot and killed.
London authorities say the fake devices looked authentic and were presumably used to hold people at bay as they executed their plot.
8 people were killed during the attack last weekend and at least 48 were injured. Among the injured ... 4 unarmed police officers.
