Russia has positioned as many as 160,000 troops along the Ukrainian front and could launch a large-scale summer offensive within days or weeks, CNN reported, citing Ukrainian military and intelligence officials. The network said recent Russian gains around the eastern towns of Pokrovsk, Kostyantynivka and Kupiansk have tightened pressure on Ukrainian supply lines. Mapping by the open-source group DeepState indicates advances toward the settlement of Rodynske, a move analysts warn could encircle Ukrainian forces if reinforcements do not arrive. The troop buildup coincides with U.S. President Donald Trump’s 50-day pause before potential secondary sanctions on Russia. Analysts told CNN the hiatus gives the Kremlin time to press its battlefield advantage. Russian Foreign Minister Sergey Lavrov dismissed the U.S. deadline, noting Moscow has weathered previous timeframes.
