British police have been out in force in Edinburgh, Scotland, Monday, where demonstrators have begun protesting the G-Eight conference of industrialized nations that opens Wednesday.

An undetermined number of arrests were reported after some of the protesters scuffled with police.  There were no reports of serious violence.

Advocates of several causes have descended to promote their causes, including representatives from anti-military, anti-nuclear, and anti-globalization groups.
