Russia has launched another massive drone and missile attack on Ukraine’s energy infrastructure, causing power outages across the country.

Russia has deployed around 170,000 troops in Ukraine’s eastern Donetsk region where they are trying to capture the stronghold of Pokrovsk in a major push for a battlefield victory, Ukrainian President Volodymyr Zelenskyy said Friday.

In rural Ukraine, attack drones are assembled in secret to strike deep into Russia. These drones target oil refineries, fuel depots, and military hubs, stretching Moscow's air defenses.

Military intelligence said the covert operation took place in 2024, but Ukraine is only now making the details public for the first time.
