The Ukrainian president says Monday's talks have been "constructive" as European leaders repeat calls for a ceasefire.

Finnish President Alexander Stubb said following the White House meeting that there had been more progress in two weeks than in over three years.

Trump made the announcement after a day of talks with Ukraine's Volodymyr Zelenskyy and a delegation of top European officials. He said he'd meet with the two leaders afterward, but did not say when.
