“Military counterintelligence has discovered the location of two hidden arsenals of weapons and ammunition in the frontline areas in the south and east of Ukraine,” the SBU said on Telegram.
It added that the weapons caches contained Grad rocket launchers, Russian-made grenade launchers and Russian anti-personnel mines which are prohibited by international law.
In Kherson, Ukrainian forces found 30 mortar and river mines and 30 grenade launcher rounds in an abandoned building of a local private enterprise.
In Dnipropetrovsk, the SBU found the weapons cache in a private house. It contained: 15 anti-personnel mines, almost 200 TNT explosive devices with detonators, a Russian Tavolga-1 rocket-propelled grenade, and more than 11,000 rounds of various calibers.
“Currently, all seized means of destruction have been sent for examination for their further transfer to the needs of the armed forces of Ukraine,” the SBU said.
It added: “In addition, in both cases, comprehensive measures are being taken to identify and bring to justice the persons involved in the arrangement of the hidden arsenals.”
