The Security Service of Ukraine (SBU) is actively identifying and disabling sabotage groups and agents of Russian intelligence services in Ukraine, the press service of the SBU reported on Sunday.

"The enemy is trying to "reactivate" the former military on our territory and involve them in both open and underground war against Ukraine. But we are successfully resisting this," the SBU said.

In particular, in Donetsk region, SBU officers detained an enemy sabotage-reconnaissance group.

"They arrived in Ukraine the day before the full-scale invasion from the temporarily annexed Crimea. They were supposed to reconnoiter checkpoints and deployment points of the Ukrainian military, as well as commit sabotage and prepare a springboard for further cleansing by the main forces of the Russian Federation," the SBU said.

During the detention, enemy intelligence officers provided armed resistance to the forces of the Armed Forces of Ukraine and the SBU. However, they were all detained. During the interrogation, the invaders provided important evidence of armed aggression against Ukraine.

In Kharkiv region, the SBU detained a fire spotter who was transmitting information to the enemy intelligence services about the location of military warehouses and critical infrastructure facilities.

"The agent cynically aimed Russian rocket artillery at residential areas of the city. As a result of these actions, the infrastructure was destroyed and casualties among the civilian population were provoked," the SBU said.

In Zakarpattia region, the SBU detained an agent of the FSB of the Russian Federation, who, from the first day of the war in Ukraine, collected data on the moods of the inhabitants of western Ukraine and their attitude towards Russia against the backdrop of the war, and in Dnipro, the Ukrainian SBU detained two local residents who spoke in support of the "Russian peace."

"According to the information received, one of the occupier's admirers photographed military facilities of the Armed Forces of Ukraine. A plan-scheme of the Operational Command Skhid of the Armed Forces of Ukraine was found in his laptop. The other collected data on the locations of checkpoints in Dnipro. He passed the information he received to the curators through the marks on the Google map about the locations of the checkpoints," the SBU said.

The SBU said that two brothers were detained in Kyiv – propagandists with pro-Russian and pro-Belarusian views. There is evidence of their close cooperation with the intelligence services of the Russian Federation and the Republic of Belarus.

"The goal of the invaders' accomplices is to undermine the internal situation in the country and create a "necessary information picture" for Russia and Belarus. So far, their picture is a view from behind the bars of the Ukrainian detention center," the SBU said.
