President of the European Commission (EC) Ursula von der Leyen says that, if necessary, the EU will expand or adopt additional sanctions against the Russian Federation in connection with the aggression against Ukraine.

"The EU fully supports Ukraine in the face of the Russian aggression. Any further aggressive acts against Ukraine will have massive costs for Russia. We can scale up and expand existing sanctions or adopt additional ones, if needed," she wrote on Twitter Wednesday morning.
