Four people have died in a fire at a hospital near the city of Hamburg in northern Germany.
The fire started around 10:45 PM local time (9:45 PM GMT) on Thursday on the third floor of the Helios Clinic in Uelzen.
About 20 people got hurt, and the police think more people might die because some injuries are really bad.
Officials are trying to find out why the fire started.
140 firefighters and people who rescue others, including some from nearby areas, worked hard to control the fire. According to reports, some people were saved from the clinic using ladders.
The police said that people inside the building called for help.
Uelzen is about 70 kilometers (43 miles) to the southeast of Hamburg.
All four people who died were patients.
However, the police mentioned that more people might have died. “There are more people who are very badly hurt and might die,” said spokesperson Michel Koenemann.
The fire is believed to have caused about €1m (£862,000) in damage.
The Helios Clinic is a hospital where doctors learn from the Hannover Medical School. The clinic’s website says it has around 750 workers and helps about 42,000 patients each year.
