Latvia issued a first air threat alert over a possible drone entering its airspace on Tuesday, telling residents near the Russian border to stay indoors, with NATO Baltic Air Police jets summoned to the area. It later said it found no evidence that a drone had entered its air space.
It declared a second air threat alert after that, over two counties bordering Russia, leading to a fresh deployment of NATO fighter jets.
"Russia continues to redirect Ukrainian drones into the Baltics with the use of its electronic warfare," Ukrainian Foreign Ministry spokesperson Heorhii Tykhyi said on X.
"We apologise to Estonia and all of our Baltic friends for such unintended incidents."
He also said Kyiv was not using Latvian or Estonian territory to launch drone attacks on Russia, which the Baltic countries echoed.
"Our legitimate military targets are located in Russia; and we use the Russian airspace to get to them," he said.
The Russian embassies in Estonia and Latvia did not immediately reply to emailed requests for comment.
Ukraine has stepped up long-range drone attacks on Russia, including around the Baltic. Since March, several Ukrainian military drones have strayed into the airspace of NATO members Finland, Latvia, Lithuania and Estonia, which all border Russia. The Latvian government last week resigned over its handling of the incursions.
In Estonia, the drone entered the country's airspace at around noon local time on Tuesday, coming from Russia and into the southeastern part of the country, the Estonian military said in a statement.
It was shot down by a Romanian NATO fighter jet on a training flight shortly afterwards, with a single missile.
"The incident occurred under the conditions of heavy electronic warfare, including GPS spoofing and jamming, by Russia," the Estonian military added.
The drone had been under surveillance before it entered Estonia, it added, with the decision to shoot it down taken to "minimise the impact on the civilian population and infrastructure".
NATO confirmed a Romanian jet had shot down a drone over Estonian airspace and said an investigation was ongoing. It said NATO "is ready and able to react to any potential air threats".
In Latvia, the air alert led to some scenes of panic in the border region with Russia, with trains suspended, national exams for ninth-grade school students stopped and grocery shops closing down, according to local media reports.
Estonia identified the drone shot down there as Ukrainian, but both Baltic states blamed the incidents on Moscow, and said Ukraine had the right to strike Russian military targets to weaken Moscow's ability to wage war.
"These incidents are the direct result of Russia's war and provocations. Estonia is strengthening cooperation with Ukraine to enhance our air defence and counter-drone capabilities," Estonia's Foreign Minister Margus Tsahkna said in a post on X.
Ukrainian President Volodymyr Zelenskiy said last week that Ukraine would send experts to Latvia to help protect the country's skies.
