Three people have died and dozens more are injured, eight seriously, after two trains collided in the west of the Czech Republic, according to railway officials.
A Munich-to-Prague service, operated by German firm Die Laenderbahn, hit a regional train between the towns of Plzen and Domazlice, which was coming from the opposite direction.
Rescuers said two of the dead were Czech drivers, one of whom was operating the German train. The third victim was a female passenger - a Czech citizen - on the regional train.
Several foreigners were travelling on the German train and some of them were among the injured, local media reported.
"Unfortunately, according to the latest information, a train collision ... has killed three and left dozens of people injured," national rail operator Sprava zeleznic said on Twitter.
"All the passengers have been evacuated from the trains," the company added.
National police said every passenger was accounted for, adding that the crash happened shortly after 8am local time (9am Irish time) near the village of Milavce.
According to footage shown on Czech public television, one part of the German train was mangled, though both vehicles remained upright.
Die Laenderbahn said in a statement that "the running of the train on the Czech side is the responsibility of the CD", the Ceske Drahy rail company.
Czech Transport Minister Karel Havlicek said: "The Ex 351 (Munich-to-Prague service) did not respect a signal ... and crashed into the regional train".
"The situation is serious," Mr Havlicek added as he headed to the scene of the crash.
Czech Prime Minister Andrej Babis tweeted his "sincere condolences to the families of the dead. It is important to save other lives. Then everything must be investigated."
"Unfortunately, this summer is full of tragedies," he added.
Four helicopters, several ambulances and dozens of rescuers were dispatched to the site.
"The German Red Cross, the Bavarian ambulance service and doctors from (the German city of) Cham are also at the scene of the rail accident," Czech police tweeted.
"German police have also offered assistance," they added.
Two train crashes in the Czech Republic in July of last year left three people dead and dozens injured.
The Czech Republic has seen several other fatal railway accidents over the years, including one that killed 118 people and injured another 100 in 1960, when the country was still a part of Czechoslovakia.
