 Kiev concerned about threat of second Belarusian front. Russia's announcement to deploy tactical nuclear weapons in Belarus increases the risk of escalation, which may require additional mobilization, according to David Arakamiya, leader of the Servant of the People faction in the Ukrainian Verkhovna Rada. So far, Kiev does not consider such a development likely, although the state border service has declared that any able-bodied men should return from abroad. Konstantin Sivkov, deputy president of the Russian Academy of Rocket and Artillery Sciences, told Russian Nezavisimaya Gazeta that the decision does not change the operational situation in the Ukrainian conflict zone since tactical nuclear weapons are not expected to be used there. At the same time, the Kiev leadership makes reference to the use of these weapons to justify additional mobilization in light of the facts that the previous call-up was disrupted. The Ukrainian nation still has mobilization resources, according to Sivkov. A second Belarusian front is within the realm of possibility, and it must be assessed objectively. Military expert at the Institute of CIS countries, Vladimir Efzeev, told. At the same time, he continued, if the Ukrainian command deemed the Belarusian direction dangerous, they would not have evacuated combat units and heavy equipment from there.
