Ukraine defies Trump as its drones hit an oil refinery in Russia's Yaroslavl and Moscow claims 856 downed overnight

Ukraine struck at least three Russian oil refineries since Friday, with a facility in Yaroslavl damaged in the latest attack, openly ignoring Trump's repeated personal requests to Zelenskyy to stop hitting Russian energy infrastructure. Russia claimed its air defences downed 856 Ukrainian drones overnight, one of the largest single interception figures of the war.

Ukraine's earlier wave of 212 drones targeted the Samara oil hub, sparking a fire at the Samara Linear Production and Dispatch Station.

Trump had specifically asked Zelenskyy to halt oil-facility strikes, citing rising global fuel prices, but Kyiv has pressed on regardless.

Russia suspended flights at Samara's Kurumoch International Airport for several hours after drone alerts swept the region.
