Probe launched into toxic sludge
Four people have died, including two children, and hundreds have been injured in a toxic spill in Hungary. The country fears this may be its worst ever chemical accident. Toxic sludge spilled out after the walls of a reservoir broke down on Monday. Industrial waste spread through several villages, destroying homes and vegetation in its path, and could soon contaminate the Danube river.
