Aachen (dpa / lnw) - Because of a cellar fire, 15 people had to leave their apartments in Aachen.

They brought themselves to safety, but complained of respiratory irritation because of the smoke, a police spokesman said on Sunday.

A resident was taken to a clinic for treatment.

After the extinguishing work early on Sunday morning, people were able to return to their homes.

The cause of the fire and the amount of damage were initially unclear.

Experts should now examine the basement.
