Sweden's military has intercepted a suspected Russian drone off the south of the country as a French aircraft carrier was docked in the port of Malmo, officials said.

The armed forces said Thursday that a Swedish naval ship observed the suspected drone during a patrol in the Oresund, the strait that divides Sweden from Denmark.

They said that unspecified countermeasures were taken to disrupt the drone and that contact with it was then lost.

The French nuclear-powered aircraft carrier Charles de Gaulle is in the southern Swedish city of Malmo this week as part of regular NATO exercise activities. Malmo is located on the Oresund, opposite Denmark's capital, Copenhagen.

French military spokesperson Guillaume Vernet told The Associated Press that the drone was detected on Wednesday and handled by Swedish forces integrated into a security system around the carrier. He said Friday that the drone was more than 6 miles from the Charles de Gaulle.

"This system showed it is robust, and this event had no impact on the activity of the aircraft carrier battle group," Vernet said.

Swedish Defense Minister Pal Jonson told public broadcaster SVT Thursday evening that the suspected violation of Swedish airspace by a drone happened in connection with a Russian military ship being in Swedish territorial waters.

Asked what country he thinks the drone belongs to, he replied: "Probably Russia."

Swedish authorities have been in close contact with Denmark about the incident, Jonson said. The armed forces said no further drones were observed.

Kremlin spokesperson Dmitry Peskov said Friday that he didn’t know about the incident. Asked by reporters about Swedish officials linking the drone to a Russian ship, Peskov said that "it’s quite absurd" to claim that the drone was Russian just because a Russian ship was nearby.

Western officials say Russia is masterminding a campaign of sabotage and disruption across Europe.

An Associated Press database has documented well over 100 incidents. Not all of them are public, and it can sometimes take officials months to establish a link to Moscow.

While officials say the campaign — waged since Russia launched an all-out war against Ukraine in 2022 — aims to deprive Kyiv of support, they believe Moscow is also trying to identify Europe's weak spots and divert law enforcement resources.
