[Updated at 9:16 a.m. ET] Four people are trapped in a coal mine in Swansea Valley, South Wales, police confirmed Thursday.
Rescue services are at the scene at Gleision Colliery, a police spokeswoman said.
Seven people were in the mine when the incident occurred, and emergency services were called soon after 9 a.m. local time (4 a.m. ET), the spokeswoman said.
Three of them got out of the mine and one has been taken to the hospital, she said, but his or her condition is unknown.
Local lawmaker Gwenda Thomas, who represents the Neath constituency in which the mine lies, near Cilybebyll, issued a statement saying she was heading back to the area.
"I am currently travelling back to Rhos community center from Cardiff. My thoughts are with all the family and friends of those currently trapped in the mine and I have confidence in all the emergency services at the scene."
A spokesman for Thomas, Robert James, told CNN the colliery was one of the few remaining drift mines operating in the area.
In a drift mine, coal is excavated from the side of a hill using shafts that are almost horizontal.

I really hope they can get them out.
Why are they looking for coal inside of a whale? Whales don't have coal. I am sure they will survive. Thanks to God, Jonah survived thanks to being put inside of a whale by His Power. It's time-proven evidence that these 4 men will survive as long as they have Jesus Christ in their hearts and call out for him to save them.
Can't tell if troll or just really stupid. Wales is an area of the United Kingdom. Wales =! whales.
Theydotoo have coal. Whales are fullofcoal. They need coal tosurvive. Read up onit.
Those are some antique whales, using coal and oil. They need to go green. NUCLEAR WHALES! Now that's where the future lies.
It's nice to see all these heartfelt comments here. What if they were your family or friends.
I would still be cracking jokes.
Yeah, you would, U-Turn.
I didn't even know we still had coal mines in Britain.
Some people killwhales to eat. They use the meat andblubber to survive. I likewhales.
Fill it in and call it good, by the way this is all obamas fault, had to be the first to say it. so tell me how its mr. presidents fault. be creative im really bored here
