Three men arrested in connection with an ongoing terror probe will be held for four weeks pending an investigation, Danish police said.
The men appeared in a Copenhagen court suspicion of illegally dealing with firearms by acquiring two automatic weapons and ammunition. They were arrested in the Danish capital on Friday.
The country's intelligence service, PET, says the arrests are linked to a terror probe and that the men were "suspected of having been in the process of preparing a terrorist act".
Preliminary charges for terrorism have not been filed.
The suspects are a 22-year-old citizen of Jordan, a 23-year-old Turkish man living in Denmark and a 21-year-old Danish national who lives in Egypt.
