Authorities search for suspected drone after waste burning triggers large smoke plume

Finnish emergency services and police investigated a suspected drone incident in Parikkala, southeastern Finland, after reports of a large black smoke plume, only to discover the cause was unauthorized waste burning, public broadcaster Yle reports.

Emergency response teams searched the Rautalahti area north of Parikkala on Wednesday and Thursday following a credible tip about thick smoke rising into the sky. By Thursday afternoon, authorities confirmed the source was a waste fire rather than a downed drone.

Police are now examining whether the waste burning constitutes an environmental offense, according to Chief Inspector Jukka Tylli. He declined to specify what materials had been burned.

Under Finnish rescue laws, residents must notify emergency services before lighting large open fires that produce significant smoke. While small bonfires are permitted on private land—common during Easter celebrations—Duty Fire Chief Toni Jaako of South Karelia Rescue Services noted that interpretation of “significant smoke” can vary.

“We prefer receiving notifications for larger fires, even if warnings aren’t in effect,” Jaako said. Records show no prior notification for the Rautalahti fire that prompted the drone search, though a separate bonfire was reported in the same area later on Thursday.

Across South Karelia, about ten bonfires were active on Maundy Thursday, with similar numbers expected over the Easter weekend.
