Russia is bringing more troops on rotation and may attempt further advances on Ukrainian soil, Ukraine’s interior ministry adviser Vadym Denysenko said.
It comes days after Vladimir Putin’s regime claimed its invasion was going to plan and hinted that it would focus on its limited goal of “liberating” the separatist-controlled Donbas region of eastern Ukraine.
Reports from the West suggest the Kremlin’s perceived shift of focus is an attempt to save face after Russia had failed to seize several Ukrainian cities.
Mr Denysenko also said in a televised address that Russia has started destroying Ukrainian fuel and food storage depots, meaning the government will have to move the stock in the near future.
Meanwhile, Putin’s regime is trying to “create a North and South Korea in Ukraine” after failing to takeover the whole country – according to Kyrylo Budanov, head of the Ukrainian millitary intelligence.
He added that Ukraine would soon launch guerrilla warfare in Russian-occupied territory.
