19:00 - Emergency declared
Tonight at 19 o'clock the mayor of the city of Jena declared a disaster situation for the city area. This happens because the district heating supply is interrupted due to an accident for large parts of Jena-North and thus about 6,500 households have to do without heating heat and hot water.

Contrary to the contact restriction regulations of the state ordinance on corona pandemic containment, it is therefore permissible for members of one household to take in all members of a household threatenedby the cold. The city of Jena will issue a corresponding general decree tomorrow. However, this regulation is effective immediately. Therefore, the city of Jena asks everyone who is able to do so to take in relatives, friends and acquaintances from these households affected by the cold. The usual hygiene rules should be observed. The city itself will organize further emergency accommodation in gymnasiums and hotels.
Until the heat supply is restored, the disaster situation will be maintained.
