During the past 24 hours four trespassers were detained in the Primorye section of the Russian-Chinese border.
The press centre of the Pacific regional administration of the Federal Frontier Service reported on Thursday that three Chinese citizens dressed in fatigues were detained in the Khasan district of the Verkhnyaya frontier post. They did not have any documents on them.
Some time later the frontier guards noticed another man who was coming from the side of the national border and detained him, too. All the four men were taken to the frontier unit for investigation.
