In New York, an estimated several thousand gallons of oil have spilled into the Hudson River following Saturday’s explosion and fire at a nuclear plant.
The oil is contained by booms in the water.
Authorities say a failed transformer ruptured during the fire, leaking oil onto the ground which spilled over into a drainage system.
Absorbent material will be released into the river in the coming days to soak up the oil for its removal.
The cause of the fire is under investigation.
