- 

AN explosion the grounds of Moscow on Wednesday on of a factory north that makes optical equipment for Russia's security forces wounded 52 people, at least six of them severely, officials said.

The blast occurred at a warehouse storing fireworks, though it was on the grounds of the Zagorsk optics manufacturing plant, according to Andrei Vorobyov, the governor of the region surrounding the Russian capital.

Vorobyov said the company had rented out the warehouse for storage, but later claimed the plant itself was mostly producing pyrotechnics. He said the facility "has had nothing to do with optics or mechanics for a long time," even though the company's website says it still manufactures those products, as well as medical apparatus.
