A village near the site of the toxic sludge spill in Hungary has been evacuated amid fears of a second wave of poisonous flooding.
Around 800 residents of Kolontar were ordered to leave their homes as a precaution after the wall of the reservoir containing the sludge was found to be further weakened.
At least seven people are known to have died as a result of Monday’s spill. It happened when the reservoir wall collapsed, sending hundreds of thousands of cubic metres of red toxic waste gushing from the alumina plant in Ajka. The waste flooded three neighbouring villages, of which Kolontar was the worst hit.
The wall has continued to deteriorate and Hungary’s prime minister says it is “likely” it will collapse again.
The caustic sludge seeped into local rivers, wiping out fluvial plantlife and fish. But fears it may have serious consequences in the Danube have eased.
A conservation group monitoring Europe’s second largest waterway has confirmed the threat to the Danube has passed.
