US road bridge collapses into Skagit River, Washington
First images from the scene of the river showed cars in the water
Part of a road bridge has collapsed into the Skagit River in the US state of Washington, officials say.
Police said some vehicles were in the water after a section of the Interstate 5 highway collapsed.
The four-lane bridge is near Mount Vernon, about half way between the state's main city Seattle and the Canadian city of Vancouver.
A state trooper reported that cars and people were in the water but it is not known if there are any casualties.
