Albanian troops and police have closed off the smoldering army depot, as the search continues for nine missing workers.
The country's prime minister says the blast destroyed more than 300 houses in a nearby village. Another 2,000 homes and businesses were damaged.
He says the accidental explosions began yesterday during a project to destroy excess ammunition stockpiled during Albania's Communist past. The prime minister calls the size of that stockpile "colossal." He says it's one of Albania's "gravest" threats.
