Russia’s emergency ministry said on Friday that at least 14 people had been killed in the south of the country after a bus carrying a group of workers plunged into the sea, the Interfax news agency reported.
Eight more people were injured, five of whom were in a serious condition, the ministry said.
There were around 40 people on the bus, which fell from a several-metre-high pier, a part of oil shipment infrastructure on the Black Sea coast.
The crash on Friday morning was likely caused by a failure in the vehicle’s braking system, said Oteko Portservice company, which runs the shipment facility.
A picture from the scene, published by the emergency ministry on its website, showed a group of divers on two boats searching waters underneath the pier.
Government investigators were looking into whether violation of security rules and traffic regulations.
