At least 48 people have been killed and dozens more injured after a train carrying nearly 500 crashed and then derailed in a tunnel in Taiwan.
The eight-carriage train reportedly hit a construction vehicle that had slipped onto the tracks at the tunnel’s mouth.
Rescuers combed badly damaged carriages inside the tunnel to find survivors, some of whom smashed windows to flee.
The train, from the capital Taipei to Taitung, was carrying people travelling for a long-weekend annual holiday.
Many people may have been standing because the train was so full.
The 408 train is one of the fastest deployed on a network that is generally considered safe. It can reach speeds of 130km/h (80mph).
Friday’s crash is Taiwan’s worst rail disaster in decades. President Tsai Ing-wen has sent her condolences to the families of the victims and ordered an investigation.
The latest reports from the National Fire Agency say 490 people were on the train, with 48 dead and some 66 injured.
Local media reports say the train driver is among the dead.
Images show a large, yellow flatbed truck lying at the side of the tracks. A construction project has been under way near the north end of the tunnel.
It is not known how the vehicle slipped down the embankment.
Other pictures showed people walking along the tracks with their belongings as they were evacuated from less badly affected carriages.
Other survivors were being carried away on stretchers with their necks in braces.
Taiwan Premier Su Tseng-chang visited the crash site on Friday afternoon.
UK Foreign Secretary Dominic Raab said on Twitter: “I offer my sincere condolences to all those affected by this morning’s rail accident in Taiwan.”
