A fire on a German tourist bus in an Alpine tunnel in Switzerland has caused the country's longest vehicle traffic jam in 19 years.
The San Bernardino tunnel has remained closed since Friday, the transport club TCS said.
Passengers avoided passage in the tunnel, where the traffic jam extended to 28 kilometers, a record length that has not been seen since 1999. The afternoon car line reached more than 20 kilometers.
The tunnel would remain closed for a week due to repairs, a spokesman said.
The bus from the German state of Bavaria went on fire, and all 20 passengers, the bus driver and the trip escort were moved to a safe place. Two people suffered minor poisoning due to smoke inhalation.
The tunnel links eastern Switzerland with the southern side of the Alps.
