Sharjah24 – AFP: NATO foreign ministers will meet on Tuesday to discuss how to counter a Russian military build-up on Ukraine's border amid fears the Kremlin could be preparing to invade.
The long-scheduled gathering in Latvia's capital Riga comes at a volatile moment on NATO's eastern flank as allies also grapple with a migrant crisis the West says is fuelled by Kremlin-backed Belarus.
Western countries spearheaded by the United States worry that Moscow could be planning an incursion into Ukraine after accusing the Kremlin of massing forces close to the frontier.
"There is not clarity about the Russian intentions but there is an unusual concentration of forces for the second time this year," NATO Secretary General Jens Stoltenberg told AFP during a visit to alliance forces in Latvia.
"We see heavy armour, drones, electronic warfare systems and tens of thousands of combat-ready troops."
Moscow, which seized Crimea from Ukraine in 2014 and backs separatists fighting Kiev, has strongly denied it is plotting an attack and blames NATO for fuelling tensions.
NATO diplomats say the bloc remains uncertain of Russian President Vladimir Putin's intentions -- but ministers will discuss contingency plans should Russia invade.
The US-led alliance is looking to show the Kremlin it faces severe costs if it threatens Ukraine, while stopping short of provoking Moscow into further aggression.
Officials expect talks on additional support for Ukraine's military and potentially strengthening NATO forces arrayed along its eastern wing.
But they point out that NATO-aspirant Ukraine -- which will have its foreign minister at the two-day meeting -- is not covered by the alliance's collective defence pact.
"We want to leave no question in people's minds that there will be severe consequences, strategic consequences for Russia, if it pursues the kind of path that we fear it may be on," a senior US official said.
"It's a question of finding the right signals and the right deterrent posture that in fact leads to a de-escalation rather than an escalation."
US President Joe Biden on Friday said he was likely to speak to the leaders of Russia or Ukraine in a push to defuse the rising tensions.
