"At our request, the U.S. Federal Bureau of Investigation will conduct a parallel examination [of former Kuchma bodyguard Mykola] Melnychenko's tapes]," Turchynov said. "FBI Director Mr. Robert Mueller and I agreed on such an examination during my visit to the United States. I don't think our two examinations will interfere with each other."
The recordings contain a voice that is purportedly Kuchma's ordering aides to deal with Internet journalist Heorhiy Gongadze, who was investigating high-level corruption.
Gongadze was kidnapped in September 2000 and his headless body was found a month later.
Kuchma has denied any involvement in Gongadze's death, which sparked mass protests.
