Ukrainian forces are increasing the intensity of long-range drone strikes deep into Russia ahead of Friday's planned meeting between Presidents Trump and Putin.

Ukraine claimed a drone strike on a helium plant close to Orenburg, Russia that produces a key component for missiles as well as the space and aviation industries, a Ukrainian official who asked not to be identified told us.

Ukrainian drones struck a major oil pumping station in Russia's Bryansk Oblast overnight on Aug. 13, according to the Ukrainian military and the Kyiv Independent's source in the military intelligence agency (HUR).
