A Danish court has sentenced three men from Germany, Colombia and Denmark to prison for the attempted smuggling and distribution of 200 kilograms (440 pounds) of cocaine, valued at more than 43 million kroner ($7 million).

The Aarhus City Court said Wednesday the men had been found guilty and given sentences ranging from one to 10 years. The men, who were not identified, immediately appealed.

The U.S. Drug Enforcement Administration helped Danish police track the movements of the men, who were arrested in Denmark in December.

Prosecutor Poul Gade said it was the first time that a Danish court ruled in a case involving foreign undercover agents.
