>> Marines storming beaches on Thursday in the latest war games held by Russia, and ahead of a major planned exercise next month. Over 2,000 servicemen involved here alongside jets, warships and rocket launchers. But some estimate next month's Zapad 2017 exercises could involve up to 100,000 troops. That would contradict a Cold War era treaty known as the Vienna Document, which requires observers for exercises involving more than 13,000 troops.
Russia has dismissed concerns from NATO allies, saying observers will be invited if more than 13,000 troops are involved, and calling next month's event a routine exercise. Russia holds Zapad war games every four years, though this will be the first since the annexation of Crimea in 2014. This week's drills taking place on the Baltic Coast in the Russian exclave of Kaliningrad.
And it's here in the Baltics where US and NATO forces have been boosting their presence, deploying four NATO battle groups of 1,000 soldiers each in Estonia, Lithuania, Latvia and Poland, all of which have a border with Russia. The US also planning 11 major exercises in a range of NATO allies, including Baltic states, next year.
Both sides it seems set to do a lot of muscle flexing.
