Ukrainian President Volodymyr Zelenskyy has reportedly accepted a proposed deal to end the war with Russia, according to a U.S. official, though “minor details” still need to be finalized.

The agreement, which has not been independently confirmed by Scripps News, was first reported Tuesday by CNN and CBS News. Both outlets quoted a U.S. official as saying Ukraine had agreed to the terms, with Zelenskyy acknowledging more work ahead before it could be completed.

The possible breakthrough follows a weekend meeting in Geneva between Ukrainian and American delegations, as well as U.S. Secretary of State Marco Rubio’s discussions with Ukrainian officials in Switzerland. Rubio described that meeting as one of the most productive to date in efforts to end the conflict.
