Ukraine bolsters its northern defences amid fears Belarus is being dragged into war

What Happened

Since January 2025, Russian spy drone incursions from Belarusian airspace into Ukraine have increased by approximately 20%, according to Ukrainian border troops. Russia has constructed five new drone bases near its shared border with Belarus, using Minsk's airspace to conduct strikes. In response, Ukraine has reinforced fortifications along its northern border, including anti-tank ditches, concrete 'dragons' teeth' obstacles, and barbed wire. A Ukrainian border force major (callsign Nissan) described the landscape and defenses as making it 'almost impossible for tanks and vehicles and infantry to move through'. Meanwhile, Ukrainian President Volodymyr Zelenskyy and other officials have warned of 'unusual activity' on the Belarus border, accusing Moscow of seeking to draw Belarus further into the war. Russia and Belarus on Wednesday accused Ukraine of conducting a deadly drone strike on a bus carrying Belarusian schoolchildren in Bryansk Oblast, an allegation Ukraine's military called 'false'. Former Ukrainian foreign minister Dmytro Kuleba stated that Lukashenko's actions differ from 2022 and he 'is preparing for war', while Ukraine's unmanned forces commander Robert Brovdi revealed that Kyiv has identified 500 targets it would hit if Belarus becomes more directly involved. There is no evidence of large troop concentrations near the border, but officials highlight joint nuclear exercises, expanded logistics infrastructure, and pro-Russian propaganda as signs of integration.

Key Actors

Why It Matters

The development marks a significant shift in Russia's use of Belarus as an enabler for airstrikes, potentially creating a wider front line and escalating the conflict beyond eastern and southern Ukraine. It tests Belarus's willingness to integrate its military apparatus with Moscow's war effort, raising risks of a direct Belarusian ground entry, despite political and military costs. The situation also threatens European security by extending the conflict geographically and increasing the chance of broader international involvement.

Watch For

Whether Lukashenko formally authorizes Belarusian ground forces under Russian command, any announcement of permanent Russian military basing on Belarusian territory, and the pace of new Russian drone base constructions. Also, diplomatic reactions from NATO and EU states regarding Belarus's role, and Ukraine's execution of its pre-identified strike list if involvement deepens.
