Our forces in the [sector] will be increased,” he said.Zelensky added that the meeting also reviewed information about Russia’s preparation of new mobilization measures involving “plus 100,000 people.”He said Ukraine currently assesses that Russia does not yet have the capacity for covert mobilization on that scale, suggesting instead that Moscow may opt for “political decisions of a different format,” including moves similar to recent actions regarding Moldova’s Transnistria region.Zelensky said Ukraine is preparing to expand the scope of long-range strikes on Russian territory, describing them as “long-range sanctions” that have already proven effective in reducing Russia’s ability to wage war.“Ukraine will definitely defend itself, and now our task is to strengthen our state so that none of the five Russian scenarios of expanding the war through northern Ukraine will work,” he said.
