A minivan full of weapons and explosives was discovered yesterday in Montreal: Explosives found in van.

MONTREAL—Police found a large stash of weapons and explosives yesterday after an investigation of a suspicious minivan tied up traffic through downtown streets for several hours.

Montreal police sent in a robot to examine several pieces of luggage after SWAT team members in full protective gear investigated the vehicle.

They seized about 15 firearms, including automatic weapons like machine guns, and also found 90-135 kilograms of explosives.

“The only good news is that the explosives and the detonators were not connected so it could not explode,” said police spokesman Miguel Alston.

Police couldn’t say what type of explosives were involved, or who they belonged to. “We cannot confirm any organization at this point,” said Alston.
