Latvian authorities have arrested the editor in chief of Russia's Sputnik state news agency in Lithuania, Marat Kasem, on a charge of violating sanctions imposed on Russia. Sputnik says a court in Riga issued a warrant for Kasem's arrest on January 5. According to Sputnik, Kasem traveled to Latvia from Vilnius due to family issues and may be charged with espionage, which has not been confirmed by any other source. The European Union banned operations of Sputnik and its umbrella company RT in March over Russia's invasion of Ukraine. To read the original story from RFE/RL, click here.
