It is a South Korea one-two with six laps to go.

We are now in the final of the men's 1500m. Nine competitors. Could be messy.

Terrifying!

Bulgaria's Pavel Angelov struggles in the men's singles of the luge as he hits the wall at speed. That has got to hurt.

Still 0-0 in the ice hockey, in a match being played in front of a fantastic atmosphere.

We have had four minutes gone as a Korea side (featuring players from both North and South Korea) takes on Switzerland and it is still 0-0.

Our reporter Caroline Chapman is there watching on, and it looks a great atmosphere.

In the ski-jump, you want to be airborne for as long as possible. In the luge, it's not a good idea.

That is what we have just incredibly seen from Slovakia's Josef Ninis. Amazingly he doesn't crash and manages to complete his second run, although it has probably left his medal hopes in tatters. Incredible.

Watch on BBC Two right now for more luge carnage.

• Elise Christie wins her heat to move into the quarter-finals of the ladies' 500m in short track speed skating, but team-mates Kathryn Thomson and Charlotte Gilmartin both crash out.
• British snowboarder Jamie Nicholls failed to make the slopestyle final after falling in his second run. Team-mates Billy Morgan and Rowan Coultas also fell in their second runs and failed to qualify, finishing 10th and 18th respectively in heat two.
• Sweden's Charlotte Kalla won the women's skiathlon to secure the first gold medal of Pyeongchang 2018, while Norway's Marit Bjorgen took silver - her 11th Winter Olympics medal - to become the most decorated female Winter Olympian of all time.

Brits Adam Rosen and Rupert Staduinger go again in the luge very soon.

Back to the men's 1500m and we now know the athletes for the final at 12:26 GMT.

Defending champion Charles Hamelin of Canada made it through by the skin of his teeth after finishing second in a photo-finish with Seo Yira of South Korea. The pair finished behind Semen Elistratov of the Olympic Athletes from Russia team.

World record holder Sjinkie Knegt of the Netherlands won heat two while heat three went to Korea's Lim Hyo-Jun, who finished just ahead of team-mate Hwang Dae-Heon.

Watch as Great Britain's Charlotte Gilmartin crashed out in the short-track 500m heats. She sustained a rib injury, but should be OK to continue in her two other events.

The Dutch - the dominant force in Olympic long-track speed skating history - could begin another gold medal rush on the opening day in the women's 3,000m.

The four-time champion Ireen Wust won the titles at Turin 2006 and Sochi 2014 and secured her 12th world crown last February - and two further honours in Pyeongchang will make her the sport's most decorated Olympic medallist.

Fellow Dutchwoman Antoinette de Jong and Canadian Ivanie Blondin should provide strong challenges, as could Natalya Voronina.

With no Russian team following the well-documented doping scandal, Voronina is likely to be competing under a neutral flag and would be a contender, having won her maiden 3,000m World Cup in December.

Elise Christie's Olympic record stood for all of about 11 minutes as South Korea’s Choi Minjeong sets a new one in the final 500m heat.

Charlotte Gilmartin was also given a penalty in that heat and despite a sore rib from her crash she’s OK to compete in the 1,000m & 1500m.

Steve Duffy: Absolutely fantastic race from Elise Christie! Olympic Record in the heats! So gutsy to really go for it after what happened in Sochi.

James Stevenson: Just the start Elise Christie would have wanted. First over the line, fastest time (so far) and an Olympic record to boot. Flying start.
