Ukrainian authorities have detained an FSB informant in Odesa who allegedly provided targeting information for Russian strikes on port infrastructure and National Guard facilities. The individual, reportedly recruited by an FSB officer in Crimea, tracked Ukrainian troop concentrations and the locations of oil refineries and logistics centers in the Odesa port.

The detained individual, described as a representative of a local food company, is accused of following instructions from an officer of the Russian Interior Ministry's department in occupied Crimea. The suspect faces up to life imprisonment.
