Ukraine launched a wave of drone attacks on Russia early Thursday — one of the largest attacks on Russia's capital since the Kremlin ordered the invasion of Ukraine more than four years ago.

July 3 (Reuters) - Russia's biggest jobs website, HeadHunter, is advertising for drone operators to protect the skies above Moscow, with no previous experience required. The online ad says candidates are being sought for a volunteer unit called the Combat Army Reserve Force that is tasked with "ensuring the capital's security using modern technical solutions and surveillance systems".

After weeks of intensifying bombing of Kyiv, Ukraine hit back with a swarm of drones, damaging buildings and igniting an oil refinery.

A large fire has broken out at an electricity substation in Lyubertsy near Moscow, leaving two districts in the Russian capital without power.

The Russian authorities said 419 drones were shot down across Russia, including in the capital, and in Crimea.

Ukraine hit Moscow with a large-scale drone attack overnight, striking one of the Russian capital’s largest satellite communication centers for the second time in a week, officials said. Kyiv fired more than 60 drones at Moscow late Monday as part of a large wave of attacks over the border that saw Russia scramble to take out 419 drones across 18 regions.

Russia has pledged to carry out frequent and "massive group strikes" against Ukraine shortly after Kyiv launched a barrage of drones on Moscow.

A third of Russia's refining capacity has been knocked out by Ukrainian drone attacks, causing petrol shortages across more than half of Russia's regions. View on euronews
