As North Korea threatens to unleash fury on the US, conspiracy theorists claim to have found 'evidence' that suggests Americans' fears should instead be focused closer to home.
An alert has surfaced on the web describing an exercise called 'Operation Gotham Shield', which will conduct a simulation crisis by detonating a 10,000-ton nuclear bomb over the New York City/New Jersey area next week.
Agencies involved in the exercise, which is said to be a routine drill, have noted that it will simulate 'a large scale terrorist attack' – but some believe it may turn into an actual disaster.
