Hungary has declared a state of emergency in three counties following a toxic red mud spill that has killed three people and left another 120 injured.
A reservoir of residue from an aluminium plant broke on Monday night, releasing corrosive sludge that swamped Kolontar and Devecser, two villages in western Hungary.
"We have declared a state of emergency in Veszprem, Gyor-Moson-Sopron and Vas counties," a government spokesperson said on Tuesday.
The sludge was reported to be threatening at least another two counties.
Al Jazeera reports, http://english.aljazeera.net/news/europe/2010/10/2010105122242999996.html, that one million cubic metres of red mud had poured out of the containment pond at the Ajkai Timfoldgyar Zrt plant.
He described the incident as the worst-ever chemical accident in Hungary, saying: "It's an ecological catastrophe".
