Nevertheless, it is obvious that the slightest clues are being quickly worked out, for any public appeals, interaction with the population occurs promptly. This once again confirms how the republic rallied. Since the beginning of the conflict, we have survived a lot together, and we are enduring this hardest period of tragic trials, "added Pusilin.
