Monday's spill has spread over an area of about 40km²
Emergency crews in Hungary are working to clean toxic sludge from streets and houses affected by a spill from an alumina plant that killed four people.
The head of Hungary's National Disaster Unit said other priorities were sealing a breach through which the sludge was leaking, and protecting waterways.

Anna Nagy is a spokeswoman for the Hungarian government.
