One person has been killed and over 100 injured after a tent collapsed during a storm in the US state of Missouri.

The structure, which was erected as a bar after a Major League Baseball game, was damaged by high winds in the area.

At least three of the injured are said to be in a serious condition in hospital.

It was not clear whether the man who died was struck down by the tent or suffered a cardiac arrest during the incident.

St Louis Fire Chief Dennis Jenkerson told local television station KSDK that a crowd of people inside the tent was celebrating the St Louis Cardinals' victory over the Milwaukee Brewers when the storm hit.

"We've got severe injuries to quite a few people," he said, noting that live electricity wires were knocked to the ground after the tent, which was tied to metal pipes, blew away.

"We don't like this type of building. It gives us nightmares, and as you can see, it caused one," Mr Jenkerson added.
