Roj TV "served as a mouthpiece for the PKK with...invitations to join the PKK and participate in terrorist actions", a Copenhagen court statement said.

The two companies behind the broadcaster were also sentenced to pay five million kroner (670,000 euros, $869,000) each in fines.

The court found "personal, financial, organisational and historical ties" existed between the accused companies and the PKK, which is considered a terrorist organisation by Turkey, the European Union and the United States.

A district court had ordered the two companies to pay fines totalling 5.2 million kroner in January 2012, but at the time did not remove the broadcaster's licence.

Danish authorities first filed charges against Roj TV in 2010 after a five-year enquiry into its broadcasts, alleging it supported the PKK.

The group took up arms in the Kurdish-majority southeast of Turkey in 1984, sparking a conflict that has claimed about 45,000 lives.

Over the years its demands have evolved from independence for the region to autonomy and protection for Kurds' culture and language.
