The head of the General Staff and the commander-in-chief of the Ukrainian Armed Forces, Army General Viktor Muzhenko, said this at a joint meeting of the Military Science Council of the Ukrainian Armed Forces and the National Academy of Sciences of Ukraine, an Ukrinform correspondent reports.
"According to military intelligence, this group currently includes more than 30,000 troops, including those deployed in Crimea," Muzhenko said.
He also noted that military groups in the occupied territories of the Donbas were controlled by the Russian command.
"The 1st and 2nd army corps numbering over 30,000 people are currently deployed in the occupied territories of Donetsk and Luhansk regions. They are managed by the newly formed 8th military army of the Southern Military District of the Russian Federation," Muzhenko said.
He said that there was still a serious threat that Russia might begin full-scale military operations.
"The main threat is the militarization by the Russian Federation of the temporarily occupied territories of Donetsk and Luhansk regions through the deployment of full-scale military groups," he said.
Muzhenko added that Russia supplies 5,000 tons of fuel and 500,000 rounds of ammunition every month for the needs of these military groups.
