Bearing Arms.com reports that there was explosion at the Sellier & Bellot factory near Prague …

A news channel in the Czech Republic is reporting that one person is confirmed dead and three are missing as the result of a gunpowder explosion at the Sellier & Bellot ammunition plant in Vlasim, 60 kilometers (37 miles) southeast of Prague.

The Google machine translation of the article is an abomination, but from what we can determine, workers were moving gun powder from a production building to a storage facility when it detonated.

A specialized hazmat firefighting unit has been brought in the secure the scene so that rescue and recovery operations can proceed.

…

It is unknown at this time how much damage was done to the facility, and how long the plant will be shut down.

Ammunition factory explosion are relatively common. I would say probably one per year somewhere in the world.
