U.S. President Donald Trump's decision to ramp up arms shipments to Ukraine is a signal to Kyiv to abandon peace efforts, Russia said on Thursday, vowing it would not accept the "blackmail" of Washington's new sanctions ultimatum.

Russia now controls more than two-thirds of Ukraine’s Donetsk region — the main theater of the ground war. Russian forces have carved out a 10-mile-deep pocket around the Ukrainian troops defending the crucial city of Kostiantynivka, partly surrounding them from the east, south and west.

Separately, on Thursday, bookmaker Star Sports offered odds of 7/2 (22.2 percent) on Trump securing the Nobel Peace Prize, placing him behind Navalnaya on 2/1 (33.3 percent) and ahead of Russian anti-war campaigner Alexei Gorinov on 6/1 (14.3 percent) and Ukrainian President Volodymyr Zelensky with 10/1 (9.1 percent).

Russia launched over 30 missiles and 300 drones during its overnight assault that affected 10 regions of the country, Ukrainian President Zelenskiy said.

Former Ukraine aid critics now back Trump's strategy requiring European funding for weapons to Kyiv after the president pivoted his frustration from Zelenskyy to Putin.
