More now on that Russian attack on a Ukrainian train which has killed five people.
Jen Stout is a freelance journalist and joins us from Kyiv, and says she's going to be travelling on one of these long-distance trains tomorrow.
"This is a lifeline train that runs between the east of Ukraine and it goes right up to the west and even further to the border towns where people are going to get out and cross into the rest of Europe," she says.
"These are lifeline trains for people with family on the front line, with husbands or wives who are fighting in the military."
Stout says that the train was carrying 291 passengers and explains what it's like inside.
"They have a lot of carriages, and the carriages have compartments," she says.
"You've got lots of people on bunk beds, so it is quite packed."
She adds that the pictures showing the train in flames are "horrific" and says it's "remarkable" so many people managed to get out.
"To see those carriages that we all travel on with the blue and white livery with the logo on the side, to see these burning and people escaping into snowdrifts is very shocking," she says.
