On the offensive
On the night of 10 May Russian troops launched an offensive in the Kharkiv region. After initially dropping aerial bombs on the area around Vovchansk, they then broke through the defence line using armoured vehicles.
The Ukrainian Armed Forces were unable to repel the attack, and Russia continued its offensive. Military expert Yury Fyodorov told Novaya Gazeta Europe that long before 10 May, Russia would have deployed a covering force in the region of some 30,000 troops and 400 tanks.
