MOSCOW (Reuters) - Russian oil company Bashneft (>> ANK Bashneft' OAO) says its operational activity has not been affected after a Moscow court seized shares owned by its parent-company oil-to-telecoms conglomerate Sistema (>> AFK Sistema OAO).

Sistema is controlled by oligarch Vladimir Yevtushenkov, who is under house arrest on suspicion of money laundering during the acquisition of Bashneft.
