Ms Barabash, who is the daughter of late literary scholar Yuriy Barabash and mother-in-law of screenwriter Lyuba Yakimchuk, was detained on Tuesday by the Russian Investigative Committee – the main federal investigating authority in Russia – a day after Ukraine marked three years of Russian invasion, according to reports.
Ms Barabash works for a Russian publication, Republic, which was added to the foreign agent media register and banned in 2022, shortly after Vladimir Putin's forces invaded Ukraine.
Russia has detained journalist and film critic Ekaterina Barabash in Moscow, her son and local media reported.
A court in Russia’s Kursk border region in January issued an arrest warrant for Jerome Starkey, defence editor at The Sun, and put him on an international wanted list.
Barabash is the daughter of late literary scholar Yuriy Barabash.
