Ukraine has struck Russia's largest oil terminal on the Baltic Sea during one of its biggest overnight drone attacks in months. The aerial assault targeted the Primorsk oil port in the Leningrad region, the final station of the Baltic Pipeline System and a crucial hub for Russia's maritime exports, Ukraine's security services told multiple outlets.

"We are dealing with a direct technological race in which the advantage will go to those who not only modernize but also stay ahead," Ukraine's Commander-in-Chief Oleksandr Syrskyi said.

Russian drones breached Poland’s airspace and, experts said, by Kremlin design or not, the incident tested NATO’s readiness to defend its easternmost members.

Ukrainian drones attacked the Russian Black Sea coast overnight into Tuesday morning, according to the Russian Defense Ministry and local officials.

Ukraine's crowdfunding groups say they've found the winning formula for beating Russia. But they're often overlooked.

President Trump said he was “not happy” about the Russia-Ukraine war after Moscow hit Kyiv with its largest drone attack since the war began, underscoring his administration’s failure so far to reach a peace deal even after his meeting with Russian President Vladimir Putin last month.

An infant was among three people who died in Russia's overnight attacks on Kyiv that injured 18 and set on fire scores of buildings in the capital, including the seat of the government, Ukrainian officials said on Sunday.

US President Donald Trump said he’s prepared to move ahead with “major” sanctions on Russian oil if NATO countries do the same.
