Russia pounded Ukraine with hundreds of drones and missiles overnight and Saturday as part of a stepped-up bombing campaign that killed at least six people and wounded dozens, officials said.

A new book alleges that President Donald Trump told donors he threatened Russian President Vladimir Putin with bombing Moscow if Russia invaded Ukraine.

The Rheinmetall Skynex anti-aircraft artillery system, now in service with Ukraine’s Air Force, is demonstrating “impeccable results” in destroying enemy strike UAVs, according to a video published by the military.

One of Russia’s most powerful men, Foreign Minister Sergey Lavrov, is set to visit North Korea this weekend, in a sign of deepening relations between Moscow and Pyongyang as North Korea gets pulled deeper into Russia’s war in Ukraine.

Officials say a Russian drone barrage has targeted the center of Kharkiv, injuring nine people and damaging a maternity hospital in Ukraine’s second-largest city.

North Korea is now supplying as much as 40% of Russia’s ammunition for the war in Ukraine as the partnership between Pyongyang and Moscow deepens, according to the head of Ukrainian military intelligence.

Kyiv was burning as Dr. Borys Todurov sped through the city in an ambulance, undeterred by the deep thuds of explosions and the terrifying sounds of Russian drones flying overhead.

"As a result of the explosion, a satellite communication hardware station—intended by Russian military leadership to coordinate occupying forces—was also destroyed," Ukraine's military intelligence said.

Russia hit the Ukrainian city of Odesa with a daytime drone strike on Friday. At least 11 people were injured, according to authorities.

President Donald Trump said he plans to make a "major statement" on Russia on Monday amid Vladimir Putin's continued attacks on Ukraine.
