ROJ-TV is currently on trial in Denmark charged with supporting the Kurdistan Workers' Party (PKK), which figures on terrorist organisation lists in Turkey, the United States and the European Union.

Politiken reported that a Danish Kurd attending a court session on Thursday discovered the diplomat was armed and reported the issue to defence attorneys, who in turn informed the judge and police.

"This is completely unacceptable. There are no special rules for diplomats. You are not allowed to carry weapons, and certainly not in a courtroom," head of the Danish Judges Association Mikael Sjoeberg told Politiken.

PET, which is responsible for diplomatic affairs, said the Turkish embassy had been summoned to a meeting Friday.

"The Turkish Embassy was called to a meeting with PET. They were told that bearing arms in a Danish courtroom must never be repeated," PET told Politiken.

"We have now taken the initiative to review all embassy personnel weapons licences in order to clarify the conditions under which these licences are given," it added.

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