LONDON -- Russia and Ukraine exchanged large waves of attack drones overnight into Sunday as the two combatants maneuvered ahead of Friday's planned summit in Alaska between U.S. President Donald Trump and Russian President Vladimir Putin.

He said Russian forces carried out 370 strikes in the Kherson direction, compared to the usual 200–250 drone attacks. Overall, strikes along the southern front increased from 400–450 to nearly 670 in a day.

Russia launched 100 drones of various types against Ukraine on the night of August 10, most of which were intercepted, though some managed to hit their targets, according to the Ukrainian Air Force on Telegram.

European nations have rallied behind Ukraine, saying peace in the war-torn nation can't be resolved without Kyiv, ahead of an upcoming meeting between U.S. President Donald Trump and Russia's Vladimir Putin in Alaska.

Ukraine’s President Volodymyr Zelenskyy defiantly declared Saturday that his countrymen “will not give their land to occupiers,” after President Donald Trump suggested that a peace deal would include some “swapping” of territories with Russia.
