Plumes of thick black smoke have been spotted above central Stockholm as a bus exploded and went up in flames after reportedly slamming into an entrance to a tunnel.

The explosion occurred on Sunday morning at the Klarat tunnel, after the bus reportedly struck its top. Witnesses say the inferno started when a gas tank located on top of the bus exploded due to the impact.

Gas driven bus exploded in central Stockholm. This was really scary! Had no idea what it was, just heard a huge explosion and started filming. Later I’ve heard on the news it was a gas driven bus that ran into a height barrier. #stockholm#explosion#gas#buspic.twitter.com/dNukg6DNpj — ΛLGΘMΨSΓIC (@algomystic) March 10, 2019

A police statement confirmed that the driver had been taken to hospital, however, his status remains unclear. Emergency services are now on site and traffic has been blocked in the immediate area and the explosion is now being treated as a traffic incident.

The Swedish Transport Administration warned that traffic in the city will be affected for the rest of the weekend. The Central Bridge, as well as the Klarat tunnel and the Soderled tunnel have been closed while emergency services clear the scene.
