Russia has sent more troops to Ocheretyne in eastern Ukraine to reinforce an offensive there, but Kyiv's forces largely hold the village and expect U.S. arms deliveries to turn the tide in their favour,

As the US prepares to transfer significant military aid to Ukraine following the Senate passing funding legislation worth $61 billion, reports from eastern Ukraine continue to highlight Kyiv’s sliding fortunes on the battlefield.

Ukraine attacked a military airfield and two oil refineries in the Krasnodar region of Russia, according to RBC-Ukraine sources. Sources say explosions rocked the Kushchevsk military airfield and the Ilsky and Sloviansk oil refineries on the night of April 27.

With future military aid looking uncertain, uncomfortable questions are being asked as to what “victory” Ukraine could realistically achieve against Russia.
