”One mouse?” The shocking cause of overnight power outage at German airport

A four-hour power outage in parts of Germany's Frankfurt Airport was blamed on a rat.
ARD broadcast on the 6th (local time) from 11pm on the 5th in some areas of Frankfurt Airport.
The power supply was cut off from 10:00 am until around 3:30 am the following day. Smoke was coming out of the transformer cables, and firefighters were called in. The report said the cause of the blackout was a rat that had chewed through the power lines.
At the time, no flights were taking off or landing at Frankfurt Airport, so there were no disruptions to flight operations. However, the baggage conveyor belt stopped, and about 1,000 bags were dropped off at random.
Two hotels near the airport were also found to have problems with their electricity supply.
