Ukraine-Russia Tensions Escalate Over Drone Incident.
Three people were injured in an explosion in Russia, which authorities blamed on a Ukrainian drone. The blast occurred 175km south of Moscow and damaged several buildings. Ukraine has not commented on the incident. The explosion comes as Kyiv calls for an emergency UN Security Council meeting to counter Russia's plan to station tactical nuclear weapons in Belarus, which Putin says is in response to the West's increasing military support for Ukraine.
