Ukraine continues to cripple Russia's energy sector by hitting numerous oil refineries, depots, chemical plants, and more with drones.

Russia launched scores of missiles and drones at Ukraine on Wednesday, targeting gas infrastructure and other energy facilities in western regions in a new barrage against the struggling power system in the depths of winter.

Ukrainian forces carried out a massive drone barrage targeting military assets in Russia. As part of its larger campaign to thwart Moscow’s advances, Kyiv launched more than 100 unmanned aerial vehicles (UAVs) along with American-made Storm Shadow missiles and Army Tactical Missile Systems (ATACMS).

Just three days before US President-elect Donald Trump returns to the White House, Russia and Iran are set to finally sign a “comprehensive partnership agreement,” a deal that’s been in the works for months.

Russian and Iranian officials say the “comprehensive strategic partnership treaty” covers all areas -– from trade and military cooperation to science, education and culture. The 20-year treaty could be extended further.

Russia unleashed a massive missile attack on Ukraine's electrical grid in the early hours of January 15, firing 43 missiles and more than 70 drones. Ukrainian air defenses intercepted 30 missiles and 47 drones,

Since the beginning of the day, more than 150 attacks have been reported along the front lines, with Russian forces concentrating their heaviest pressure in the Pokrovsk direction, reports the General Staff of the Armed Forces of Ukraine.
