Russia says Ukraine launched major drone attack, including on Moscow

MOSCOW, ‌Dec 11 (Reuters) - Russia said on Thursday that Ukraine ‍had ‌launched a major aerial attack with at least 287 ⁠drones downed over ‌a number of regions including Moscow.

Russia's defence ministry said at least 40 drones were shot down over the ⁠Moscow region, which along with the city itself has a population ​of more than 22 million.

The extent ‌of the damage was ⁠not immediately clear but flights were diverted from at all of Moscow main airports.

Russia invaded Ukraine ​in February 2022 and currently controls a little under one fifth of Ukrainian territory.

Russia has pummelled its smaller neighbour with missiles and drones, recently ​targeting ‍its energy sector. Ukraine ​this year sought to knock out Russian oil refineries and oil terminals with drones.

Ukrainian sea drones on Wednesday hit and disabled a tanker involved in trading Russian oil as it sailed through Ukraine's ⁠exclusive economic zone in the Black Sea to the Russian port of ​Novorossiysk, a Ukrainian official said.

War insurance costs for ships sailing to the Black Sea have spiked, with insurers reviewing policies daily as ‌the conflict in Ukraine spills into sea lanes.
