A year that opened with a relatively quiet stretch along the Baltic states’ eastern borders has, by late July, turned into one of the more incident-heavy periods since 2022 — a shift border guard agencies in Latvia, Lithuania and Estonia attribute to a mix of deliberate pressure tactics and the ordinary friction of policing one of the EU’s most sensitive frontiers.
Winter and spring: isolated incidents
The first months of 2026 saw a handful of GPS jamming reports near the Latvian-Russian border and occasional attempted crossings by migrants funnelled through Belarus, consistent with patterns established over the previous two years. Border guard officials described the period as tense but manageable within existing protocols.
May–June: drone incursions increase
The pattern shifted in late May, when Lithuanian and Latvian authorities each recorded multiple unauthorised drone incursions in a single week, some flying several kilometres into national airspace before being tracked and, in two cases, forced down. Officials stopped short of directly attributing the incursions to Russian state activity but noted the timing coincided with heightened NATO discussions ahead of this month’s Ankara summit. Estonia’s Internal Security Service reported 14 confirmed drone incursions in the first half of 2026 alone, compared with 9 for the whole of 2025, a year-on-year increase officials call consistent with a broader pattern rather than an isolated spike.
July: a new peak
This month has brought the sharpest escalation yet, with Estonia reporting a significant undersea cable disruption in the Gulf of Finland under investigation as a possible act of sabotage, and Latvia recording its highest monthly count of attempted irregular border crossings from Belarus since the current barrier system was completed in 2023.
Why officials describe this as strategic pressure, not coincidence
Security analysts point to the timing relative to Latvia’s October election and the broader NATO summit calendar as more than coincidental, arguing the cluster of incidents fits a pattern of low-intensity pressure designed to test response times and sow uncertainty without crossing into open conflict — a concern also raised in recent commentary on Baltic security coordination. Frontex has also increased its operational presence along the Belarus border sections in Latvia and Lithuania this summer, part of a broader EU effort to support member states facing sustained migratory pressure linked to what officials in Brussels have repeatedly described as state-orchestrated instrumentalisation of migrants.
How the response has evolved
All three countries have expanded joint patrol arrangements and accelerated planned investments in border surveillance technology, including additional radar coverage and underwater monitoring equipment for critical infrastructure. Officials describe this year’s incidents as a stress test of systems built up since 2022 — one that, so far, they say has held, even as the frequency of incidents climbs.
