The European Union has agreed to sanction six individuals and one organisation from Russia over the poisoning of leading dissident Alexei Navalny, EU diplomats say.
The agreement came at a meeting of EU ambassadors in Brussels, and follows a decision to get started on new sanctions that was taken by the bloc's foreign ministers on Monday.
The asset freezes and travel bans are to be finalised by written procedure and could be implemented within a few days.
Navalny, a fierce critic of President Vladimir Putin and prominent anti-corruption campaigner, fell ill on a domestic flight in Siberia on August 20 and was transported to Germany for treatment in a comatose state two days later.
Last week, the Organisation for the Prohibition of Chemical Weapons (OPCW) confirmed that the Soviet-developed nerve agent Novichok - a banned warfare agent - was used in the attack.
