Acting Assistant Attorney General Nicole Argentieri, and other officials and representatives of international organizations, according to Ukrinform.

In Berlin, Kostin also held meetings with his German counterpart Lars Otte, German Justice Minister Marco Buschmann, and Vice-President of the Bundestag Katrin Goring-Eckardt.

They discussed coordinating the work with Ukrainian victims and witnesses of Russian war crimes who currently live in Germany and ensuring their access to justice, according to Kostin's office.
