Russia’s top general announced that President Vladimir Putin has ordered the expansion of a buffer zone in northeastern Ukraine in 2026.

The move, targeting Sumy and Kharkiv regions, comes amid ongoing tensions along the Russia-Ukraine border.

Chief of the General Staff Valery Gerasimov told Russian news agencies that Putin directed the expansion of territory Moscow calls a buffer zone. He inspected the “North” troop grouping, which was formed in early 2024 to operate in northeastern Ukraine.

The “North” grouping has been working to establish a buffer along the border, attempting to push back Ukrainian forces to secure further advances. Russia claims the expansion is intended to keep Ukrainian forces and weapons farther from its border, citing cross-border shelling and drone attacks on regions such as Belgorod and Kursk.

Kyiv rejects Russia’s buffer zone plans

President Volodymyr Zelenskiy has dismissed Moscow’s plans as “mad” and emphasized that Ukraine will resist any further incursions into Sumy and Kharkiv. Kyiv has consistently rejected Russia’s buffer zone concept, calling it a pretext for deeper territorial advances.

Gerasimov’s statement follows Russia’s vow to retaliate against what it alleged was an attempt to attack Putin’s residence—claims Kyiv denied, asserting the allegation aims to undermine peace talks. There has been no immediate official reaction from Ukraine regarding the Gerasimov report.

Regional implications

The expansion of the buffer zone signals continued military pressure in northeastern Ukraine, raising concerns about potential escalation. Analysts note that Russia may use the buffer zone justification to intensify operations while framing it as defensive.

Observers will be watching how Ukraine responds militarily and diplomatically to Russia’s planned expansion. The situation underscores the fragile nature of the conflict as it nears its fourth year.
