President Donald Trump told reporters Sunday that his administration is prepared to move ahead with the second phase of sanctions on Russia over its ongoing war against Ukraine.

Russia fired more than 800 attack drones and 13 missiles at cities across Ukraine on Saturday night and early Sunday, in Moscow's largest aerial assault since launching its full-scale invasion in 2022.

US President Donald Trump has voiced frustration with Moscow following Russia's largest-ever aerial assault on Ukraine, even as his administration signalled tougher sanctions to "collapse" the Russian economy,

Russia hit Ukraine with more than 500 drones and missiles in a deadly attack that saw NATO jets in neighboring Poland scrambled to defend its airspace.

Russia launched a record aerial assault on Ukraine in the early hours of Sunday. 805 large strike drones and 13 missiles were launched. Ukrainian air defences intercepted 747 of the incoming projectiles. At least 11 people were killed and 75 injured across Ukraine, but rescue operations are still ongoing, and those numbers could change.

The Kremlin dismissed the threat of new Western sanctions on Monday, with spokesman Dmitry Peskov insisting they would not alter Russia’s stance in Ukraine. The comments came as US President Donald Trump signaled readiness for a “second phase” of sanctions.
