COPENHAGEN (Reuters) - A Copenhagen court found a Danish pizzeria owner guilty on Wednesday of joining Islamic State (IS) to fight in Syria, the first such case in the Nordic country.

The verdict comes amid concerns of increased radicalization among Muslims in Europe and deadly attacks claimed by Islamic State militants in Paris and Brussels.

The court found the 24-year-old defendant, who holds both Danish and Turkish passports, guilty of allowing himself to be recruited in 2013 by IS in order to commit terrorist acts in Syria.

The man, who was arrested in March 2015, had denied fighting for IS, but admitted to having worked as a baker for the group in Syria.

He is expected to be sentenced later on Wednesday.

Danish authorities have been on high alert since two people were killed in shooting attacks at a free speech event and at a synagogue in Copenhagen in February 2015.

In April Danish police arrested four other people suspected of having been recruited by IS to commit terrorist acts and two others of breaking Danish weapons law.

More than 125 people from Denmark are believed to have joined IS after going to Syria and Iraq, the intelligence service said in October, adding that at least 27 of them had died there.
