LONDON -- A spokesman for Europol tells The Associated Press that the European police agency is setting up a task force of more than 50 experts to help northern European countries investigate terrorism in the wake of the deadly attacks in Norway.

Spokesman Soeren Pedersen says the group, which is based in The Hague, will help in investigations in the coming weeks.

He said Saturday that right-wing groups "are getting more profesisonal, more aggressive in the way they attract others to their cause."
