The Ukrainian Air Force says Russia has launched a major aerial attack on Ukraine, firing 574 drones and 40 missiles.

Russia launched 614 air attack munitions into Ukraine overnight into Thursday, the air force in Kyiv reported, in what the country's Foreign Minister Andrii Sybiha called a "massive combined air strike" on targets around the country.

As Trump pushes for peace, Ukraine accuses Russia of a deadly drone and missile strike, "as if there were no efforts by the world to stop this war."

Russia has targeted Ukraine’s cities in the largest combined drone and missile attack in more than a month, only five days after Donald Trump’s meeting with Vladimir Putin in Alaska.

There are too many drones and only so many frequencies. Friendly jamming happens, sometimes as an accident, sometimes in panic.

Russian troops currently control about 20% of Ukrainian territory, but the Ukrainian constitution forbids giving up territory or trading land.

Russia said Wednesday attempts to resolve security issues relating to Ukraine without Moscow's participation were a "road to nowhere," and that much diplomatic work needs to be done before Vladimir Putin and Volodymyr Zelenskyy are ever in the same room.

As negotiations over the war carry on, President Vladimir Putin is pushing hard with tactics that have evolved over three and a half years.
