The owners of a Russian bank filed a lawsuit against the online publication BuzzFeed on Friday for publishing an uncorroborated dossier that alleged they were part of a Russian scheme to influence the 2016 U.S. presidential election.

Mikhail Fridman, Petr Aven and German Khan of Alfa Bank are seeking unspecified damages from BuzzFeed, editor-in-chief Ben Smith, reporter Ken Bensinger, and editors Miriam Elder and Mark Schoofs.
