The deployment took place in Sumy Oblast, a northeastern region bordering Russia that has recently faced renewed Moscow's attempts to advance.

Ukraine's Air Force said Russian forces launched 136 drones overnight, including Iranian-designed Shahed-type attack drones, and fired four S-300/400 guided missiles.

"There are many topics to discuss," Ukraine's Presidential Office head Andriy Yermak said.

Russian Shahed-type drones regularly breach Belarusian airspace as they fly towards Ukrainian cities during mass attacks which have escalated significantly over recent weeks.

The number includes 1,130 casualties Russian forces suffered just over the past day.

Moscow's ongoing summer offensive has not reached the Kremlin's expectations as Ukrainian troops continue to thwart Russian attacks on various regions, President Volodymyr Zelensky claimed on July 13.

U.S. Senator Lindsey Graham said in an interview with CBS News on July 13 that he expects an influx of U.S. weapons shipments to Ukraine to begin "in the coming days," as U.S. President Donald Trump prepares to make a "major statement" on the war in Ukraine on July 14.
