Ukraine says it has detained a 25-year-old Uzbek national on suspicion of spying for Russia.
The State Border Guard Service (DPS) says the suspect was detained at a border checkpoint on September 19 while entering Ukraine's eastern Kharkiv region from Russia.
The DPS said border guards found a camera hidden in a button on the suspect's clothes as well as video- and audio-recording devices in his pockets.
The Uzbek citizen, whose name was not disclosed, told border guards that he received the devices from Russian officials after he was detained in Russia for staying in the country illegally.
The suspect was handed over to Ukraine's Security Service for further investigations.
