**Deck**: Intelligence chiefs from Czechia, Latvia and Sweden say Russian sabotage across Europe is set to intensify, with defense industry facilities and rail networks that support Ukraine singled out as likely targets.

Intelligence leaders from Czechia, Latvia and Sweden are warning that Russia is preparing more sabotage operations on European territory, and that the focus is shifting toward physical damage to the infrastructure that keeps Ukraine supplied.

They say Moscow is increasingly targeting defense industry sites and rail networks across Europe, with the aim of weakening support for Ukraine. The warning points to a pattern that goes beyond online disinformation or cyberattacks and into direct disruption of factories and transport routes.

For workers at arms plants, train operators, and the communities around them, that means facilities once seen as routine industrial sites are now potential targets in a wider confrontation. Security at these locations is likely to tighten, with more checks, surveillance and restricted areas.

Europe’s rail system is central to moving heavy weapons, ammunition, fuel and humanitarian cargo eastward, but it wasn’t built to be guarded like a front-line asset. Even small, well-planned acts of sabotage — damage to a key yard, bridge or signaling system — can delay large volumes of cargo and force military planners to find workarounds.

Strategically, the intelligence chiefs’ warning underlines that Russia views the broader European support network for Ukraine as fair game, even if it avoids open acknowledgment. By hitting logistics and defense production sites that sit far from the battlefield, it can try to slow the flow of supplies while staying in a grey zone below the threshold of open military confrontation.

European governments now have to decide how far to go in hardening rail lines and industrial plants without making everyday life feel like it’s under permanent emergency rules. That requires closer coordination between intelligence services, police, private security and companies that until recently did not see themselves as part of a high-stakes security picture.

For Ukraine, delays or interruptions along these routes can translate into shortages at the front weeks later. Disruptions hundreds of kilometers away from the war can ripple through to artillery stocks, spare parts and fuel near the line of contact.

Clear signs that this threat is materializing would include a cluster of unexplained fires or explosions at industrial or rail facilities, criminal cases tied to foreign-directed sabotage, extra security investments around key transport hubs, and new public warnings from European institutions about hybrid threats. If major cargo routes have to be rerouted or heavily guarded, the cost and complexity of sustaining Ukraine’s war effort will rise — precisely the effect these operations are meant to achieve.
