Ukraine's border guards say Russia has begun moving troops into Ukraine's Crimea region by ferry.
According to Reuters, border guards say Russian troops have seized control of the border post on the Ukrainian side of the waterway, and are now ferrying truckloads of soldiers across.
Earlier on Monday, Ukrainian border guards said they had seen Russia assembling an armoured column on its side of the 4.5-kilometer wide Kerch strait, that separates the Crimea peninsula from southern Russia. Russian troops have been surrounding the ferry terminal for days.
