Two trains have collided in southern Poland, killing several people and injuring around 60 in what appears to be one of the country's worst rail disasters in recent years.
Polish media broadcast images of warped white and green train carriages that appeared to be derailed. The cause of the collision, which occurred north of Krakow in the small town of Szczekociny, was not immediately clear.
One of the trains was travelling from Warsaw to Krakow and the other was heading from the eastern city of Przemysl to Warsaw, news agency PAP reported.
"Everything indicates that this is one of the most serious railway catastrophes of recent years in our country," transport minister Slawomir Nowak told TVN24. "There are people who have died, there are many injured people."
It was not immediately clear how many people might have died. Emergency officials put the number of injured at around 60, according to reports by TVN24 and PAP.
Mr Nowak said he was on his way to the site of the accident with prime minister Donald Tusk.
Dozens of rescue workers and helicopters were deployed to help those injured.
