Volodymyr Zelenskiy has said Ukraine’s military incursion into Russia’s Kursk region aims to create a buffer zone to prevent further attacks by Moscow across the border, Ednews informs via The Guardian.

It marked the first time the Ukrainian president had clearly stated the aim of the operation, which was launched on 6 August. Previously, he had suggested it aimed to protect communities in the bordering Sumy region from constant shelling.

In his nightly address on Sunday, Zelenskiy said: “It is now our primary task in defensive operations overall to destroy as much Russian war potential as possible and conduct maximum counteroffensive actions. This includes creating a buffer zone on the aggressor’s territory – our operation in the Kursk region.”

Kyiv had previously said little about the goals of its push into Russia with tanks and other armored vehicles, the largest attack on the country since the Second World War, which took the Kremlin by surprise and led to scores of villages and hundreds of prisoners falling into Ukrainian hands.

The Ukrainians drove deep into the region in several directions, facing little resistance and sowing chaos and panic as tens of thousands of civilians fled.

Ukraine’s commander in chief, Gen Oleksandr Syrskyi, claimed last week that his forces had advanced across 1,000 sq km (386 sq miles) of the region, although it was not possible to independently verify how much territory Ukrainian forces effectively control.

In his remarks on creating a buffer zone, Zelenskiy said Ukrainian forces “achieved good and much-needed results”.

The Institute for the Study of War has “observed claims” that Ukraine’s operation in Kursk advanced through 800 sq km over its initial six days. The incursion “attacked largely unprepared, unequipped and unmanned Russian defensive positions along the border”, the US thinktank said in its daily report on the conflict. Ukraine had continued to make rapid advances in Kursk “following the deployment of Russian reinforcements to the area”, it added.
