Two trains collided in northern Greece, killing at least 32 people and injuring dozens more, according to emergency services.
Rescuers have been working all night to free passengers from one of the trains that crashed near the city of Larissa.
The train, which was carrying 350 passengers, collided with a freight train.
Thick plumes of smoke rose from derailed carriages, according to footage posted on local news websites.
According to the fire department, 150 firefighters and 40 ambulances were on the scene.
The cause of the collision with the passenger train, which was traveling between Thessaloniki and Larissa, is unknown.
“We heard a big bang,” said passenger Stergios Minenis, according to Reuters.
“It was a terrifying ten seconds. We rolled around in the carriage until we fell on our sides and the commotion stopped. Then came the panic. Fire, cables. The fire started right away.
“We were being burned as we turned over. Right and left, there was fire… It was chaos for ten to fifteen seconds. People screaming, people trapped, buildings collapsing, fires raging, cables dangling, windows shattered. “It was two meters up from where we jumped to leave, and beneath it was broken iron debris, but what could we do?”
Another passenger, Angelos Tsiamouras, told local media that the collision felt like an earthquake.
Another passenger named Lazos told Protothema newspaper the experience had been “very shocking”.
“It was a very powerful collision,” Kostas Agorastos, regional governor of the Thessaly region, told state-run television, according to AP news agency. “What a terrible night… The scene is difficult to describe.”
Because of the “severity of the collision,” conditions for rescue workers were “very difficult,” according to fire service spokesman Vassilis Varthakoyiannis.
