Estonia's Minister of Foreign Affairs Marina Kaljurand wears a yellow ribbon in support of Estonian police officer Eston Kohver as she listens during a news conference in Riga, Latvia, August 19, 2015. Kohver, allegedly abducted by Russia in a cross-border raid, was sentenced to 15 years in prison on Wednesday, further stoking tensions between Moscow and the former Soviet republic. Russia arrested Kohver on espionage charges in September last year, saying the Estonian was caught on Russian territory, but Tallin maintains he was taken at gunpoint at a border crossing.
