Earlier Monday, Russian President Vladimir Putin made a rare visit to Minsk, extolling the benefits of cooperation with neighboring ally Belarus, stoking fears in Kyiv that plans for a joint ground offensive are in the works.Belarusian President Alexander Lukashenko has said repeatedly he has no intention of sending his country's troops into Ukraine, after providing Russian troops with a launching pad for the invasion in February.Asked about this comment, U.S. State Department spokesperson Ned Price said it should be treated as the "height of irony," given it was "coming from a leader who is seeking at the present moment, right now, to violently absorb his other peaceful next-door neighbor."Belarusian Hajun, a crowdsourced channel monitoring movement of Russian military equipment and weapons, reported that Russia transferred at least 50 Ural military trucks and another 30-truck convoy to Belarus over the past week."The capacity of the Russian military, even reinforced by elements of the Belarusian armed forces, to prepare and conduct effective large-scale mechanized offensive operations in the next few months remains questionable," the think tank said in an assessment published Sunday."
