Dozens of people are feared dead after a packed train derailed inside a tunnel in Taiwan on Friday at the start of a long holiday weekend, with rescuers still scrambling to reach others trapped inside.
The train was traveling to Taitung when it came off the rails as it entered a tunnel, just north of the city of Hualien.
At least four people are believed dead, and three people with serious injuries have been sent to hospital and around 20 with light injuries are waiting to go to hospital, it said.
Another live broadcast by UDN outside the tunnel showed at least two undamaged train carriages with rescuers helping passengers escape.
Taiwan's Transport and Communications Minister Lin Xia-lung said on Twitter that he was on his way to the crash site.
"Around four people are without life signs", the Central Emergency Operation Center said in a statement, adding rescuers were trying to get to four carriages inside the tunnel that were badly damaged and hard to access.
The official Central News Agency said a truck "not parked properly" was suspected of sliding into the path of the train.
