Fire at rebuilt Kaiser's palace in Berlin

Fire broke out Wednesday at the central Berlin site where the German imperial family's palace is being reconstructed, injuring one and sending black smoke pouring into the sky.

The fire broke out outside the building in two tar kettles, causing a propane gas cylinder to explode before around 80 firefighters extinguished the blaze.

"Pictures of fire above the entrance to the palace sent shivers down all our spines," junior minister for culture Monika Gruetters said in a statement.

One worker was slightly hurt by smoke inhalation, firefighters said.
