Donetsk Oblast (Ukraine) (AFP) – In Ukraine’s eastern Donetsk region, the scene of some of the war’s longest-running and bloodiest fighting, soldiers hold positions just a few hundred metres from the enemy. For the Ukrainian 68th Brigade, not far from the city of Vugledar, the only thing separating them from nearby Russian troops is a wide and heavily mined field, littered with the wreckage of armoured vehicles.
