A toxic leak from an aluminum plant reservoir in western Hungary flooded several villages last week, killing seven people and injuring more than 100.
Part of the red sludge reached the Danube, one of Europe's main rivers.
As European Union experts attempt to find out how badly the toxic spill has damaged the environment, Hungarian authorities continue frantically building dikes in case the dam holding the sludge breaks further, the government said Monday.
If you or a loved one has been affected by the toxic sludge, please share your images and stories with CNN.
