One person died in a fire in a refugee accommodation in Hamburg on Monday.
"The forces have found a full fire on the upper floor of a container system here," said a fire department commander of the German Press Agency.
The firefighters immediately started extinguishing and rescue work in the refugee accommodation in the Winterhude district: "Squads wearing respiratory protection penetrated inside and unfortunately could only find a missing person lifeless with certain signs of death."
A police spokesman said in the evening that the identity of the dead was still unclear.
Fire investigators have started work.
A total of around ten containers were destroyed or damaged by the fire, said the fire department spokesman.
The background to the fire reported around 5:30 p.m. is completely unclear.
The fire brigade was at the scene of the fire with three fire engines and 75 emergency services.
Residents were asked via the Nina-Warnapp to keep windows and doors closed because of the heavy smoke development.
The warning was lifted just before 7 p.m.
The fire was out around 8:00 p.m. and clean-up work began.
According to the municipal operator Fördern und Wohnen, the container accommodation in the Hamburg-Nord district offers almost 500 places for refugees and homeless people.
The containers are close together and each consist of a ground floor and a first floor.
A spokeswoman for funding and housing told the "Hamburger Morgenpost" ("Mopo"): "We assume that a building housing the accommodation in Tessenowweg is now uninhabitable." Alternative accommodation is now being organized for ten residents.
