Ukraine's military reportedly struck the Nevinnomyssk Azot plant in Russia's southern Stavropol Krai overnight on May 20, Russian Telegram media channels reported.

The facility on the Black Sea Coast was previously hit three times in two weeks, causing heavy damage to the refinery and triggering a state of emergency in the city.

The Hungarian government under Viktor Orban had already filed a similar case, though it is unclear if the incoming pro-European government of Peter Magyar wishes to take it forward.

Russian forces launched 123 drones against Ukraine overnight, of which about 80 were Shahed-type ones, the Air Force said on April 28. It reported downing 95 of them.

President Volodymyr Zelensky said those brought back to Ukraine include individuals against whom Russian authorities have opened criminal cases, as well as wounded soldiers.
