Russia overnight attacked targets across Ukraine with 241 drones and five missiles, striking energy infrastructure and killing two civilians, according to Ukraine's air force and government officials.

Despite the finding, the authorities have been unable to fix the damage from a drone that punctured Reactor No. 4’s outermost protective shield in February.

Ukraine said in February a Russian drone had struck the protective shelter housing the nuclear reactor at Chernobyl, the site of the world's worst nuclear disaster in 1986. A fire at the site was quickly extinguished, Ukrainian President Volodymyr Zelensky said at the time. Russia denied targeting the site.

After a number of drone sightings near European airports and military bases, mysterious aircraft were seen over Ireland as Ukraine's Zelenskyy visited.

NATO fighter jets were scrambled and air defense systems put on alert in Poland in response to Russia’s latest overnight drone and missile strikes in Ukraine.

Ukraine is increasingly using interceptors to destroy Russian drones, and its best pilots are often young videogame aces.

President Donald Trump is claiming Ukrainian President Volodymyr Zelenskyy “isn’t ready” to sign off on a U.S-authored peace proposal aimed at ending the Russia-Ukraine war.

Photos emerging from the battlefields of Ukraine show a strange, spiky new "hedgehog" armor being used on tanks and armored vehicles to protect the hardware from drone strikes.
