Germany: Fire breaks out at Berlin metal factory

German firefighters battled on Friday to control a fire that broke out at a metal technology factory in the southwest of the capital, Berlin.

Dark smoke rose from the complex, located in Berlin's Lichterfelde neighborhood.

Firefighters said sulphuric acid and copper cyanide were stored at the plant, and when the chemicals ignited, hydrogen cyanide could have formed.

The fire brigade issued a hazard warning but later said hazardous substances were only detected in the air in the immediate vicinity of the Diehl Metall plant, not in the smoke that drifted toward the city center.

As a precaution, nearby schools sent students and staff home, and several shops in the area were closed.

"The building is now completely burned through on four floors. Part of the building has already collapsed," Adrian Wenzel, the Berlin fire department spokesman told Bild. 

According to the spokesman, there were no injuries. All people were able to evacuate the area.

It wasn't clear what caused the fire. 

Diehl Metall is a subsidiary of the German Diehl Group, which manufactures the IRIS-T missiles, which are also used in Ukraine. 

A company spokesperson, however, said no armaments had been manufactured at the Berlin facility.
