"Kyiv is striving to provoke a regional conflict by any means," Alexander Volfovich told the Russian state-owned outlet Sputnik Belarus.The incident happened while Russia was firing dozens of missiles at cities across Ukraine in one of the biggest waves of strikes of the conflict.He compared it to an incident in November, when an S-300 believed to have strayed after being fired by Ukrainian air defences landed on the territory of NATO-member Poland, triggering fears of an escalation that were rapidly defused.Nevertheless, the Ukrainian ambassador was summoned to the foreign ministry in Minsk on Thursday to receive a formal protest about the "extremely serious" incident.Though Minsk has repeatedly said it does not intend to participate directly in the conflict, a flurry of military activity in Belarus, including the formation of a joint Russian-Belarusian unit, has aroused fears in Kyiv and the West that Russia may launch a fresh offensive from Belarusian territory."
