A group of pro-Ukrainian forces said on Friday they were fighting Russian troops on the outskirts of a village just inside Russia's western border, a day after Moscow said it had repelled three cross-border attacks.
The attacks follow a major incursion into Russia's western Belgorod region on May 22-23 and an increase in cross-border shelling in recent weeks as Ukraine prepares to launch a big push to recapture Russian-occupied land in its east and south.
