Two men from the US state of Iowa are being charged with weapons offensives after they threatened to attack the Pokemon World Championship in Boston.
Police arrested the two, 18-year-old Kevin Norton and 27-year-old James Stumbo, on Saturday and found illegal weapons and ammunition in their car.
Norton and Stumbo allegedly used social media to make threats against participants in the event.
Boston police say they are looking into whether the suspects are connected to any terror organizations.
