"Over the past 24 hours of hostilities, all Ukrainian soldiers have remained safe and sound," Lysenko said at a briefing in Kyiv on Thursday.

Tension and armed provocations continue along the entire line of contact, stretching from the Sea of Azov to the village of Stanytsia Luhanska.

The fiercest fighting took place in the town of Adviyivka on Wednesday, where militant used tanks and artillery against Ukrainian soldiers, Lysenko said.
