Hungary says it will cost tens of millions of dollars and take at least a year to clean up the damage caused by a spill of industrial toxic red sludge.

Emergency workers are trying to stop the spill, from an alumina plant, from flowing into major waterways, including the River Danube

A state of emergency has been declared in three western counties after the chemical waste burst from a reservoir.
