(CNN) -- Authorities were evacuating a Hungarian village Saturday after they found new damage in the reservoir that caused a toxic sludge spill this week, an emergency services spokeswoman told CNN.
Hungarian Prime Minister Viktor Orban, who was visiting the stricken area Saturday, said it was "very likely" the reservoir wall will collapse.
"It's in very bad shape, and our estimation is that that wall could fall down," Orban told reporters in the town of Ajka. "One consequence is that human lives could be in danger. That's the reason why we pulled out ... all human lives from that area, in order not to have more loss in human life".
If the wall collapses, 500,000 cubic meters of red sludge could spill out -- half of the amount that spilled out Monday, the prime minister said.
