Terrorists arrested in Denmark...

It seems like about once a week, there are arrests somewhere...indicating how big this problem is.

Police arrested four Danish Muslims Thursday on suspicion of belonging to a terror network planning a suicide attack in Europe, officials said.

The suspects, all males between 16 and 20 years old, were ordered held in jail while police investigate the allegations, police spokesman Joern Bro said.

He said at a news conference that the network had planned to carry out the suicide attack in Europe.

"It seems the plan was going into a closing phase," said Bro, declining to provide further details.

The suspects, who were not further identified, faced a judge in a closed-door hearing late Thursday in Glostrup, a suburb of Copenhagen.

Police said they raided the suspects' homes in the Copenhagen area, seizing computers, computer discs, books with radical Muslim literature and cellular phones. Some 25 people in all were briefly detained but only the four were arrested.

Danish media quoted Bro as saying that the arrests in Copenhagen were linked to an investigation in the Balkans in which arrests were made this month and large quantities of explosives were found.
