Hungary sludge could hurt Danube
Bucharest - An environmental group says Hungary's sludge spill that killed at least four and injured more than 100 could trigger long-term damaging effects for life in and along the Danube.
An official with the International Commission for the Protection of the Danube says it "has potential implications for other countries".
Philip Weller, the group's executive secretary, also said on Wednesday the commission's early warning alarm system was triggered by the spill, which meant factories and towns along the Danube may have to close water intake from the river.
The Vienna-based commission, which manages the river's waterways, is waiting for details of the spill from Hungarian authorities.
