The Dzhankoi checkpoint is located in the north of Crimea and borders the Kherson Region.
"At the Dzhankoi checkpoint, in the course of inspection measures on a car traveling to the territory of the Republic of Crimea, employees of the Federal Security Service of Russia have found an object similar to an explosive device attached to the bottom of a car under the driver's seat driven by a law enforcement officer of the Kherson region," the spokesperson said.
The car has been promptly moved to a safe distance, after which explosive ordnance disposal specialists defused the device, he said.
"According to the conclusion of experts, the explosive device is made of foreign-made components supplied to the territory of Ukraine by NATO countries," he added.
Law enforcement is investigating the incident and is looking into the circumstances of the crime and for the people involved.
