More than 100 believers have been arrested in North Korea after gathering in a secret worship meeting. 

The now face being persecuted because of their faith. 

They have been sent to a political prison, where the conditions are inhumane and reported to be worse than those on the notorious Auschwitz concentration camp during World War II.

The inmates are treated as animals and tortured and forced into doing harsh labour with little food.

In North Korea it is illegal to worship Jesus or even own a bible.

The country is number two on Open Doors watchlist, a Christian charity that supports persecuted Christians around the world.

Ex prisoner Hae-Woo who is a North Korean believer has encouraged people to pray for the families that have recently been imprisoned.

She said: "While I was in prison, I could not understand everything, but I felt the Christians in different countries praying for us who were imprisoned.

"It provided comfort, and it became a source of energy for us. Even if we cannot meet each other, let us communicate through the Spirit, in Jesus Christ.

"Let's pray together and make good out of it. I hope our Lord will be glorified. 

"I believe at God's appointed time, all the prayers will be answered and there will be freedom of faith in North Korea. 

"Let us endure in patience and wait until that day comes."
