Danish intelligence warns of possible attacks

"There are renewed indications that terrorist groups abroad are looking to send terrorists to Denmark to commit terrorist attacks," the Danish intelligence agency PET said in a statement. PET however said the level of threat against Denmark was unchanged.

"There is still a serious terror threat against Denmark... particularly since the reprinting of cartoons of Prophet Mohammed in February 2008, which means that Denmark and Danish interests are a priority terrorist targets," the agency said.

It called on police to be "extremely cautious" until the end of this year. "In light of the threats in Denmark and other European countries, PET has asked the country's police to pay more attention to the terrorist threat until the end of December 2010," PET head Jakob Scharf said in a statement.

In September, PET issued a statement saying Denmark was a priority target for terrorist attacks after a terror suspect in detention in Norway confessed  that the Danish daily Jyllands-Posten which published caricatures of the Prophet Mohammed was his target. In another case, a Chechnya-born man arrested in Copenhagen in September was allegedly preparing a letter bomb to target the same daily.
