Two men from the Dutch city of Arnhem were arrested in Germany in August on suspicion of travelling to Syria to fight in the civil war, the Dutch public prosecutor confirmed on Tuesday.
The confirmation came after a report in tv news programme Nieuwsuur on Monday evening. Around 100 Dutch nationals are thought to be serving with rebel groups in Syria.
According to Nieuwsuur, the two men, aged 21 and 26, were arrested on the request of Dutch authorities. They have yet to be extradited to the Netherlands, news agency ANP reports.
The men were arrested in Kleef in a car stocked with military clothing, cash, iPhones and sim-cards, Nieuwsuur said. One man is reported to have an older brother already in Syria.
