TO GO WITH AFP STORY BY DMYTRO GORSHKOV A Ukrainian border guard mows the grass on July 2, 2015 along the barbed wire fence on the Senkivka border post, around 200 kilometres (125 miles) north of the Ukrainian capital Kiev. The freshly-dug ditch running along a short stretch of metal fence topped with barbed wire marks the start of a new border defence that Ukraine hopes will protect it from Russia. Dubbed the "Wall", the ambitious project to seal up Ukraine's porous 2,000-kilometre frontier with it's ex-Soviet neighbour was announced in March 2014 after Moscow seized the Crimea peninsula from Kiev.
