Ukrainian drone units have carried out a series of successful attacks on the Russian-occupied Donetsk Airport, sabotaging Moscow's attempt to turn the facility into a military base, Ukraine's Unmanned Systems Forces (USF) reported on June 4.

Russian missile, drone strikes kill at least 22 people across Ukraine, authorities say, after President Zelenskyy warned Moscow was planning a "massive new strike."

June 4 (Reuters) - The Russian-installed management at Ukraine's Zaporizhzhia nuclear power plant accused Ukraine on Thursday of deploying more than 20 drones to attack a nearby thermal plant vital to supplying the facility with external power.

The 412th Nemesis Brigade calls the Morrigan its "secret weapon" in the mid-range, a new style of attack Ukraine has been intensifying recently.

The Russian drone struck an apartment building, wounding two people, Romanian officials said.

Russia's own long-range strikes against Ukraine also continue. Ukraine's air force said it faced a record-breaking 8,361 Russian munitions -- 8,150 drones and 211 missiles -- in May, of which 55% of missiles and 90% of drones were intercepted or otherwise failed to reach their targets.

Romania's foreign minister said ​on Wednesday several allies were preparing to reinforce air defence capabilities along NATO’s eastern ‌flank after a drone identified by Bucharest as Russian crashed into a residential building on its territory.

Ukraine denied Moscow's claims that a Ukrainian drone struck the Russian-controlled Zaporizhzhia nuclear plant, as Kyiv launched new strikes on Russian energy sites.
