Russian military prosecutors have canceled an arrest warrant for Ukraine's ex-Prime Minister Yulia Tymoshenko.

A brief statement Monday by the prosecutor-general's office in Moscow says the warrant was canceled because Ms. Tymoshenko appeared for questioning in the Russian capital during the weekend. Russian authorities say the former prime minister pledged to return for further rounds of questioning in the future.

Ms. Tymoshenko was named Ukraine's prime minister after last year's "orange revolution," which toppled a pro-Moscow administration and brought President Viktor Yushchenko to power in Kiev. However, she was dismissed after just seven months in office, following a dispute with Mr. Yushchenko.

Ms. Tymoshenko has been accused of bribing Russian defense officials while she headed a Ukrainian energy company 10 years ago. She contends the Russian charges are politically motivated.
