The Ukrainian security service (SBU) says it has foiled a Russian plot to assassinate President Volodymyr Zelensky and other high-ranking Ukrainian officials.

Two Ukrainian government protection unit colonels have been arrested.

The SBU said they were part of a network of agents belonging to the Russian state security service (FSB).

The Ukrainian leader said at the start of the invasion he was Russia's "number one target".
