Some three million people have been left without power after violent storms hit the region around the US capital, Washington DC.
The storms swept from the Midwest states to the region around Washington, packing winds of up to 80mph (130 km/h).
The power outages left many sweltering without air conditioning amid a record-breaking heatwave.
