Seven dead after bus falls into river in St Petersburg

Seven people have died after a bus crashed and fell into a river in the Russian city of St Petersburg, according to local officials.

The accident took place on the Potseluev Bridge over the Moika River in the historic city centre on Friday afternoon.

Footage shows the bus swerving into oncoming traffic, colliding with two cars before breaking through the bridge barrier and falling into the water - sinking within seconds.

The driver of the bus has been detained and a criminal investigation into the cause of the crash has been launched, authorities said.

Russia's investigative authority announced the increased death toll via a statement on Telegram on Friday evening.

It came after earlier reports from local authorities stating four people were left in critical condition and two others were seriously injured after the crash.

An estimated 20 people were reportedly on board at the time of the incident.

It happened after the driver of the bus lost control when turning into the bridge from Bolshaya Morskaya Street.

"Rescuers took nine people out of the sunken bus," the Emergency Ministry said on social media. However, three people were reported dead shortly after.

CCTV footage from the scene appears to show passers-by jumping in to the water to attempt to rescue passengers.

According to Russian reports, Idris Gadzhiev, Shahban Jabrailov and Muhammad Hasanov were among those who jumped into the river.

"We were driving to Friday prayers when we saw the bus falling into the river," Mr Gadzhiev told the Fontanka website.

"We weren't being heroes but just fulfilling our civic duty," Mr Jabrailov said.

Footage later released by the authorities shows emergency services lifting the bus out of the river using heavy machinery.

The Emergency Ministry later said rescue operations had been completed.

The Potseluev Bridge is in the centre of St Petersburg, around 1.5km (0.9 miles) from the Hermitage Museum.
