A Danish appellate court on Friday stripped a man of his Danish citizenship for volunteering to fight for the extremist Islamic State in Syria.
Danish-born Hamza Cakan, who has dual Danish-Turkish citizenship, was also to be deported to Turkey after serving a six-year prison sentence, the Eastern High Court said.
The 25-year-old Cakan, formerly known as Enes Ciftci, had travelled to Syria twice in 2013 and was registered as a "fighter" by Islamic State, according to the appellate court.
Defence attorney Michael Juul Eriksen said the deportation would be appealed to the Supreme Court.
Cakan was last year sentenced to seven years in prison but allowed to keep his Danish passport.
It was the second time the citizenship of a Danish national was revoked due to terrorism crimes. In June, the Supreme Court ruled that Moroccan-born Said Mansour was to lose his Danish citizenship after he was sentenced in 2014 to a four-year prison term for inciting terrorism and urging support for al-Qaeda.
