For what is technically peacetime, there’s a lot of shelling going on round here. Donetsk airport is still held by the Ukrainian army and the rebels of the Donetsk People’s Republic bombard it furiously every day. The Ukrainians reply by lobbing back artillery shells and Grad missiles. Both sides bristle with anti-tank and anti-aircraft missiles, so the war is a static one, fought by a series of artillery duels, first world war-style.
