"He is a citizen in Yemen," Anna Ekberg, who works with the press service at the Swedish Foreign Ministry, told TT. According to the foreign ministry, the 19-year-old man has a Swedish residence permit.
According to a police officer that Associated Press spoke with, the other man is a Swedish citizen in his late 20s who was released from prison in 2011 after serving six years for possessing explosives and threatening to carry out a terrorist attack. He was arrested and convicted in Bosnia and served part of his sentence there before being transferred to Sweden to serve out the remainder.
The Swedish embassy in Athens is working to get more information about the case concerning the two men, who according to the ministry, live in southern Sweden.
Greek police say they have arrested two men suspected of possessing weapons and attempting to travel to Syria to join the Islamic State group, writes AP.
