Ukrainian counterintelligence investigators have foiled a Russian plot to assassinate President Volodymyr Zelenskyy and other top military and political figures, Ukraine's state security service said Tuesday.

Two colonels in the State Guard of Ukraine, which protects top officials, were detained on suspicion of enacting the plan drawn up by Russia's Federal Security Service, a statement said. The colonels were recruited before Russia’s full-scale invasion of Ukraine in February 2022, according to the statement.
