A major Russian oil and gas production platform in the Caspian Sea has halted production after a first-of-its-kind Ukrainian drone attack, multiple news outlets reported Thursday, citing Ukraine’s Security Service (SBU).

The Comoros-flagged Dashan was sailing through Ukraine’s exclusive economic zone in the Black Sea towards the Russian port city of Novorossiysk when it was attacked by agents from the SBU. The ship had its automatic identification system switched off at the time of the strike, an SBU source said.

Russian drone and missile attacks in and around the Ukrainian capital killed at least three people early Saturday, officials said.

A large-scale Russian drone and missile attack damaged power facilities in eight Ukrainian regions, causing blackouts and forcing nuclear power plants to cut power output, officials and the International Atomic Energy Agency (IAEA) said on Saturday.

KYIV, Ukraine (AP) — Russia unleashed a major missile and drone barrage on Kyiv early Friday, killing six people, leaving gaping holes in apartment buildings and starting fires as the sound of explosions boomed across the city and lit up the night sky.
