Swedish royals tour Estonia.

Sweden's King Carl XVI Gustaf and Queen Silvia began a three-day state visit to Estonia, their first official visit to the former Soviet republic in more than 30 years. The visit will focus on boosting cooperation between the two countries in the security and defense sectors, economy, and education, research, and innovation. Estonia has historical links to Sweden, as the small nation was a province of the Swedish Empire in the 17th and early 18th centuries.
