Massed Russian aerial attacks using long-range drones have been a near-daily occurrence over Ukraine in the past several months, as Moscow looks to exhaust Kyiv's air defences alm

Snow, sleet, fog, the lot; when the weather is at its worst is when Russian soldiers tend to go out on assault. After a day and night of steady snowfall, the sky begins to clear just before dawn, during the silent drive to Ukrainian drone positions south of Kupiansk in Kharkiv Oblast.

Russia was once again in flames today as a suspected Ukrainian drone strike' devastated a chemical plant in Vladimir Putin's home city of St Petersburg, leaving a "pillar of fire". Huge repeated explosions were heard at the facility in Gatchina - which makes acetone that can be used for military explosives and rocket fuel.
