As Ukraine drone attacks on Russian oil ports in the Gulf of Finland continued on Sunday morning, the Finnish Defence Forces (FDF) sent fighter jets to southeastern Finland on surveillance patrols.
The FDF has said that the F/A-18 Hornet fighters are on the lookout for drones that could stray into Finland.
Yle's Nato correspondent Maria Stenroos said she was woken up on Sunday morning in Kouvola by the sounds of the fighter jets and managed to capture them on video.
"Based on sound and visual observations, I would estimate that the Hornets were flying at an altitude of around one kilometer," Stenroos said.
She said the surveillance detail continued in the area for about an hour.
The most recent attack in the region was reported on Sunday morning at Russia's Baltic port of Ust-Luga, not far from Estonia's border. In a post on social media platform Telegram, Governor of Leningrad Oblast, Aleksandr Drozdenko, reported that the Ust-Lugan oil port had been damaged.
He said Russia had shot down nearly 30 of the drones sent by Ukraine, and that there were no casualties.
However, no drones have strayed into Finnish airspace.
The agency has not issued further information about the matter.
Finnish fighter jets were also sent over densely populated areas of southern Finland, following Ukrainian attacks on Russian oil ports on the Baltic Sea on Thursday and Friday.
It was reported that a Ukrainian drone strike on Wednesday had damaged an icebreaker and an old Finnish building in the Russian city of Vyborg, about 40 kilometres from Finland's eastern border.
