President Volodymyr Zelenskiy said on Friday he had visited the northern Sumy region, from where Ukraine launched a major incursion into the neighboring Russian Kursk region in August.
Almost two months into the surprise incursion, Kyiv's troops control swathes of Russian border territory, though the pace of the advance has slowed and Moscow's forces have begun to counterattack.
"It is crucial to understand that the Kursk operation is a really strategic thing, something that adds motivation to our partners, motivation to be with Ukraine, be more decisive and put pressure on Russia," Zelenskiy said on Telegram.
Shown alongside his top army commander, Oleksandr Syrskyi, visiting the 82nd Air Assault Brigade, the president thanked the military for defending Ukraine's territorial integrity.
He said the incursion, which Ukraine says is bringing war back to Russia, "has greatly helped" Kyiv to secure the latest military support packages from the West.
"We need to motivate the whole world and convince them that Ukrainians can be stronger than the enemy," he told the servicemen.
Zelenskiy added that he had held a meeting with his military command, which had discussed the front lines and the energy situation in the Sumy region. Russia has been pummeling regional electricity infrastructure, leading to power cuts.
