Ukraine attempted to deflect news that it was responsible for the 14 April attacks, instead asserting that Russian intelligence services were trying to "carry out terrorist acts to whip up anti-Ukrainian hysteria" in the country. According to the Ukrainian news agencies Interfax-Ukraine and Euromaidan Press, after the attack the  Security Services of Ukraine released an unverified alleged conversations between Russian soldiers in which they state that Russia deliberately fired on the villages in order to blame Ukraine. One of the Russian soldiers told his wife that the attack was "ours", and that it was done to "pretend that Ukrainians provoke (Russia)." The conversation also makes a reference to Russian apartment bombings in 1999 which served as a pretext for the launch of the Second Chechen War and which some historians and journalists believe were a false flag operation by Russian security services to help Putin assume presidency. In response  to accusations regarding the April 13 Bryansk border checkpoint incident by Russia's FSB security service, Ukrainian interior ministry advisor Anton Herashchenko said that something "fell and caught fire" at a Russian military facility, without explicitly confirming or denying Ukrainian responibility. On April 25, Ukrainian Lt. General Ihor Romanenko said "We will not just watch them hit our railway stations, fuel and lubricant processing plants, and so on. The time has come for this to happen to them as well.” On 27 April, Mykhailo Podolyak, advisor to Volodymyr Zelenskyy, commented on the recent incidents. Without directly admitting that Ukraine was  responsible, he said that it was not possible to "sit out" the Russian invasion. "And therefore, the disarmament of the Belgorod and Voronezh killers' warehouses is an absolutely natural process. Karma is a cruel thing," he said.
