¡¡¡¡MOSCOW, Oct. 31 (Xinhuanet) -- Russian prosecutors on Friday unfroze part of the Yukos shares that they had seized a day earlier, Interfax reported.

¡¡¡¡The step was taken one day after the prosecutors on Thursday froze about 44 percent of the Yukos's shares owned by two foreign companies, claiming that the move was to prevent "material damage". ¡¡¡¡

¡¡¡¡Last week, Russian police arrested Yukos' chief executive Mikhail Khodorkovsky and accused him of committing several economic crimes.

¡¡¡¡On Friday, the Prosecutor General's Office said that the shares have only been seized, not confiscated.

¡¡¡¡Earlier, Russian Prime Minister Mikhail Kasyanov said that he was "deeply concerned" by the freezing of shares of Russia's largest oil producer. Enditem
