LVIV, Ukraine — Russian forces freed the mayor of the Ukrainian city of Melitopol in exchange for nine of their captured conscripts, an official from Ukraine’s presidential office said Wednesday.

Kyiv accused the Russians of kidnapping Mayor Ivan Fedorov about a week ago. Surveillance video showed him being marched out of city hall apparently surrounded by Russian soldiers.
