Three people are believed to have died and one is feared missing after a train derailed in Scotland, Sky News said Wednesday, citing PA Media, in what has been declared a major incident.
The British Transport Police force said officers were called at 9:43 am (0843GMT) to the railway line near Stonehaven, about 100 miles (160 kilometres) northeast of Edinburgh, where a train had derailed.
Police, several ambulances, an air ambulance and fire engines were at the scene.
First Minister Nicola Sturgeon tweeted that it was "an extremely serious incident".
"I've had an initial report from Network Rail and the emergency services and am being kept updated. All my thoughts are with those involved," she said.
British Prime Minister Boris Johnson said in a tweet that it was a "very serious incident" and "my thoughts are with all of those affected".
Local lawmaker Andrew Bowie said one hospital in nearby Aberdeen had declared a major incident.
Stonehaven is on the line for passenger trains linking Aberdeen with the cities of Edinburgh and Glasgow. The hilly area was hit by storms and flash flooding overnight.
"We obviously don't know why the derailment took place, but obviously we have suffered terrible weather here," Bowie said.
Serious train accidents are rare in the UK. The country's last fatal derailment was in 2007.
