The tense body language perhaps says it all. German chancellor Angela Merkel being welcomed on a rare visit to Russia by President Vladimir Putin. The pair met in the Black Sea resort of Sochi, for talks ahead of the G20 summit. Ties have been strained between Moscow and Berlin on issues including the conflicts in Syria and Ukraine. Now this is Merkel's first trip to Russia since the annexation of crimea in 2014. She called on all sides to work towards a ceasefire in the region.
