Russia alleges that dozens of Ukrainian militants crossed into one of its border towns in its Belgorod region, striking targets and forcing an evacuation, before over 70 of the attackers were killed or pushed back by what the authorities termed a counterterrorism operation.
Ukraine denied any involvement in the skirmishes Monday and Tuesday, instead blaming two Russian groups that claim to be volunteers fighting alongside Kyiv's forces in an uprising against the government of President Vladimir Putin.
