WARSAW, July 6 (Xinhua) -- Six people were injured in Warsaw after a city bus collided with a tram and multiple cars before crashing into a pedestrian underpass, Polish media reported.
The accident occurred at around 6 p.m. local time (1600 GMT) on Sunday. The bus, operating on Route 186, first collided with a tram before continuing toward a roundabout, where it struck 14 cars.
Police said the 58-year-old bus driver reported a possible technical malfunction that may have affected the vehicle's braking system. Tests showed that the driver was neither under the influence of alcohol nor drugs.
Traffic disruptions were cleared late Sunday after the damaged bus was towed from the underpass shortly after 11 p.m. Traffic around the roundabout has since returned to normal. ■
