Drones launched by Ukraine overnight crossed into Estonian and Latvian territory as part of a wider strike on Russian Baltic ports, authorities in Tallinn and Riga said.
One unmanned aircraft struck the chimney of a power plant in Auvere, Estonia, while another fell and detonated in Latvia’s southern Krāslava region.
Officials reported no serious damage or injuries.
The incidents happened around the same time Kyiv carried out a major drone attack on the Russian port of Ust-Luga, about 25km from the Estonian border.
Estonia’s prime minister said the assault came in three waves between roughly 03:00 and 08:00 local time, prompting Baltic air patrols and public alerts about a drone threat.
Estonian security officials said the device that hit the power plant appears to have left its intended flight path, possibly after being disrupted while over Russian airspace.
Latvia’s leader also confirmed the drone that landed on Latvian soil was Ukrainian in origin.
Latvia’s defence minister cut short a visit to Ukraine and returned home after the incident.
The Latvian deputy chief of the joint staff said the craft likely veered off course or was knocked off track by countermeasures such as electronic warfare, which can interfere with GPS guidance.
Officials stopped short of blaming Kyiv for deliberate wrongdoing, noting such mishaps are an indirect consequence of Russia’s full-scale invasion.
They also warned that neighbouring countries cannot feel entirely immune while military operations continue next door.
A similar case was reported in Lithuania on Monday night, when a Ukrainian attack drone crashed and exploded near the Belarus border.
Lithuanian authorities later confirmed the drone had been part of operations against Russia and said they would coordinate with Ukraine on airspace safety.
Ust-Luga is a major oil-export terminal and the reported strike there caused a fire that local authorities later brought under control.
Kyiv has increasingly targeted Russian energy infrastructure, including ports and refineries, in recent weeks.
Officials said nearly 400 Ukrainian drones were fired toward various Russian regions overnight, including the Moscow area.
The developments come after Russia launched its largest 24-hour drone assault on Ukraine last week, firing close to 950 drones and causing casualties.
Estonian security chiefs warned that similar cross-border incidents could recur, and the country’s prime minister dismissed the idea that a physical border barrier would prevent such risks.
Baltic governments say they will press for clearer communication and measures to protect civilian airspace as the conflict extends across the region.
