At least 36 people were killed and dozens more injured when a train derailed in Taiwan on Friday after apparently colliding with a truck.
44 people had been sent to hospital, officials said, as the island faced its worst rail disaster in decades.
Taiwan’s Red Cross said it was on the scene and helping to free passengers trapped in the crash.
“Our emergency services have been fully mobilized to rescue & assist the passengers & railway staff affected,” Taiwanese President Tsai Ing-wen said on Twitter.
“We will continue to do everything we can to ensure their safety in the wake of this heartbreaking incident.”
The train was carrying around 350 people, the country’s fire department said, thought to include many tourists and people heading home at the start of a long holiday weekend.
Images of the crash scene show some carriages inside the tunnel ripped apart from the impact, while others crumpled, hindering rescuers reaching passengers.
Photos showed passengers clambering over the sides of the train to safety as rescue efforts continued.
The official Central News Agency said a truck “not parked properly” was suspected of sliding into the path of the train. The fire department showed a picture of what appeared to be the truck’s wreckage next to the derailed train.
The express service traveling from the capital Taipei to Taitung on the southeast coast came off the rails while part of it was inside a tunnel north of Hualien in eastern Taiwan, the fire department said.
The accident came on the first day of the four-day Tomb Sweeping Festival, an annual religious festival when people travel to their hometowns for family gatherings and to worship at the graves of their ancestors.
Taiwan is a mountainous island where most of its 24 million people are squeezed onto flatlands along the northern and western coasts. The lightly populated east is popular with tourists, many of whom arrive along the coastal railway lines to avoid treacherous mountain roads.
The railway line from Taipei down the east coast is renowned for its tunnels and route that hugs the coast just north of Hualien where the crash occurred.
Taiwan’s extensive rail system has undergone substantial upgrades in recent years, particularly with the addition of a high-speed line connecting the capital Taipei with cities to the south.
