Turkish authorities said on Thursday that a suspicious object found on the shore in Sakarya's Karasu district on the Black Sea coast was an unmanned surface vessel (USV) that did not contain explosives.
The incident occurred at around 3:45 p.m. local time on the Denizkoy shore in Karasu.
Teams from the Karasu Law Enforcement Support Command were dispatched to the area after citizens reported seeing a suspicious object on the beach.
Following coordination with teams from the Underwater Defense (SAS) Group Command, initial examinations found that the object was a USV and that it did not carry explosives.
In line with instructions from the Karasu public prosecutor, the vehicle was taken under protection by teams from the Karasu Law Enforcement Support Team Command to be destroyed.
The discovery was the latest in a series of incidents involving unmanned systems found along or near Türkiye's Black Sea coast.
On Monday, an unmanned aerial vehicle (UAV) was found in a field in the Taskopru district of Kastamonu province. Authorities believe it crashed after losing communication with its operator.
The incident occurred near the road in the Cansa neighborhood of Orhenli village in Taskopru.
It was not the first such incident in Kastamonu this year.
In late June, a fixed-wing drone came down in the province, one of several similar incidents reported around the same period in neighboring Black Sea provinces, including Samsun and Bartin.
Since late 2025, Turkish authorities have recorded a series of drone discoveries along and near the Black Sea coast, most assessed to be linked to the ongoing Russia-Ukraine war.
Devices have been found or have crashed in provinces including Ordu, Zonguldak, Bartin, Samsun, Artvin, Balikesir and Istanbul.
In several cases, examined drones were assessed to be of Russian origin, including Geran-2 models based on Iran's Shahed-136 design. Others were identified as Ukrainian-type or unidentified systems.
Some devices recovered in these incidents were found to be armed and required controlled destruction by explosive ordnance disposal or naval commando teams.
Others, including a Russian-assessed drone found on the Ordu coast in February, were confirmed to contain no explosives before being handed to police for technical examination.
Turkish officials have previously said they are closely monitoring the risks posed by drone incursions and remain in contact with relevant parties to help prevent the war from spreading and avoid further escalation.
No indication has been given in the Karasu case as to the USV's origin or ownership.
