Ukraine’s security service (SBU) says it has taken down a Russian “spy network” in the Kharkiv region.
“The criminals collected intelligence on the geolocation of fortifications and routes of movement of military equipment columns of the defence forces, including by rail,” it said.
Four alleged members of the network were arrested as part of the “multi-stage operation”, the SBU said.
“During the searches of the detainees’ residences, computers and mobile phones were found, which they used to conduct reconnaissance and subversive activities against Ukraine. Three combat grenades were also seized from them.”
Three were charged with high treason, while the other was charged with the illegal handling of ammunition – while the SBU is still searching for another man, who is believed to have fled to Russia.
The four in custody face up to life imprisonment.
