Authorities in both countries said that the drones had come in from Russian airspace, with Riga saying that the projectile that landed in Latvia appeared to be Ukrainian.
“A drone struck the chimney of the Auvere power plant. No one was injured in the incident,” the Estonian internal security ISS said in a statement, adding that “the drone entered Estonian airspace from Russian airspace.”
The Auvere power plant, operated by the Enefit Power group, is located in northeastern Estonia, near the town of Narva on the Russian border.
“These are the effects of Russia’s large-scale war of aggression,” said ISS Director General Margo Palloson, expressing concern about “the occurrence of such incidents in the future.”
Prosecutors are supervising an investigation into the incident.
Latvian Prime Minister Evika Silina said on her X account, however, that the drone that fell on Latvian territory was apparently Ukrainian.
Ukraine carried out several strikes against Russia overnight, in particular targeting the major northwestern port of Ust-Luga on the Gulf of Finland.
The two Baltic countries are along a possible trajectory for drones targeting the region not far from Saint Petersburg.
Latvia’s air force said it had identified an unmanned aerial vehicle travelling in Latvian airspace from Russia and that its early warning system detected a sound similar to an explosion in the Kraslava region.
Kraslava is the southeastern corner of Latvia that borders Belarus, an ally of Russia.
Latvian authorities said there were no injuries or damage caused by the explosion and that the wreckage of the drone had been recovered.
