Sudden winds in St Louis, Missouri, USA blew over a tent outside a sports stadium killing at least one person and injuring about 100 others.
The tent had been set up as a beer garden.
A man who was under the tent when it collapsed, had a heart attack and died.
The incident happened about 3.50pm on Saturday, just after the St Louis Cardinals baseball game ended.
Witnesses said a sudden gust lifted the tent, sending metal poles flying.
