"Russia does not conduct any negotiations and we do not need such negotiations. The investigation is underway. Within the investigation negotiations are a request of the court or the investigator, and there should be an answer," he said at a briefing in Kyiv on Wednesday.
Nalyvaichenko said: "I think the court and the investigation will have questions to the Russian Federation - who gave the order, the commander of which unit, which commander, which commander-in-chief and the entire hierarchy that gives orders and makes its citizens - servicemen of the Russian Federation - to go to our territory killing people and looting. "
Earlier, the Russian consul visited the two Russians in Kyiv hospital.
GRU servicemen Aleksandrov and Yerofeyev were detained by Ukrainian soldiers near Shchastia on May 16. On May 20 they were notified of suspicion of involvement in terrorist activities as part of the "LPR".
