The Erna Raid annual international military exercise has begun in Estonia. It commemorates a reconnaissance group that worked with German military intelligence in World War Two. Moscow believes that the exercise is an attempt to glorify Estonia's collaboration with Nazi Germany. The Erna unit was a Finnish Army formation of Estonian volunteers, that spied behind Red Army lines. The event's been held since 1994, with teams from around the world taking part.
