Two more men suspected of belonging to a terrorist network planning a homicide attack in Europe were arrested in Denmark (search), police said Saturday.

The two men, who were not identified, are suspected of assisting four young Muslims arrested in Copenhagen Thursday on charges they were planning an "imminent" terror attack.

The two suspects, described only as young men, were to face a preliminary court hearing later Saturday, police officer Ole Schultz (search) said.

"They will then be charged with assisting terror attempts," Schultz said without elaborating.

The arrests were made Friday.

Danish police have said the four men arrested on Thursday are linked to the arrests of a Turkish, Swedish and Bosnian national in Sarajevo on Oct. 19-20 on suspicion of preparing a terrorist attack.

Police said they found explosives, firearms and other military equipment in connection with those arrests. The Bosnian national has since been released.

No weapons or explosives have been found in connection with the Danish arrests, police said.

Danish police are working with Bosnian investigators on the case but said it is still unclear where the alleged terror attack was intended to take place.

According to Sarajevo's Dnevni Avaz (search) daily newspaper, one of the three suspects arrested in Bosnia was an 18-year-old preparing a suicide attack on the Sarajevo embassy of a European Union country. Police have not confirmed the report.

Terrorists have not hit Denmark in 20 years, but the London bombings in July stirred fears that the Scandinavian country could be targeted for its participation in the U.S.-led coalition in Iraq, where Denmark has about 500 troops.

In 1985, a bomb detonated outside the offices of North West Orient (search) airlines in Copenhagen, killing one person and wounding 16. Three Palestinians living in Sweden were convicted of planting the bombs and sentenced to life in prison in 1989.
