The committee said on its website that "armed Ukrainian formations targeted and deliberately fired at a group of Russian journalists" working near Pyatikhatka, in Ukraine's southeastern Zaporizhzhia region.
It did not specify the type of weapons or munitions used, but said Rostislav Zhuravlev, a journalist for RIA state news agency, was killed.
It said his RIA colleague and journalist Konstantin Mikhalchevsky, and two employees of Izvestia newspaper, Roman Polshakov and Dmitry Shikov, were injured.
Ukraine, which received supplies of cluster munitions from the United States this month, has vowed to use them only to dislodge concentrations of enemy soldiers.
Both sides have used cluster munitions during Russia's 17-month invasion of Ukraine.
