Russia said on Monday its military hit Ukrainian air bases in overnight strikes and Ukrainian forces shelled industrial facilities inside Russia as both sides sought the upper hand ahead of what Kyiv hopes will be a decisive counter-offensive.
In a rare acknowledgement of damage to a military "target", Ukraine said that work was under way to restore a runway and that five aircraft were taken out of service in the western region of Khmelnitskiy, though it did not name the sites.
