The reporters were in Qatar due to the fact that it is one year until the World Cup starts.
They reported on the criticism of the World Cup, the lack of human rights and the situation of migrant workers in the country.
They had been in Qatar since November 14, but just before they were to fly home, they were arrested.
Two days later, they have now been released.
- We are first and foremost very happy and relieved that both are safe and on their way home.
I talked to them early today.
They were affected by what they had been through.
This case has had the highest priority with us, says NRK manager Thor Gjermund Eriksen.
NRK has not received any explanation for the arrest of the journalists.
