Ukraine's Security Service (SBU) has almost completed investigation into an alleged genocide of Ukrainians during the 1932-1933 Holodomor famine, the presidential press service said Tuesday.

President Viktor Yushchenko held a conference on Tuesday on the investigation into the case.

"[Deputy SBU chief] Nikolai Gerasimenko has reported that the case has almost been investigated and its materials will be handed to the Prosecutor General's Office within a week," the press service said.

In late 2006, Ukraine's parliament recognized the Stalin-era famine known as Holodomor as an act of genocide by the Soviet authorities.

Russia says the famine cannot be considered an act that targeted Ukrainians, as millions of people from different ethnic groups also lost their lives in vast territories across the Soviet Union.

Kiev has been seeking international recognition of the famine as an act of genocide. Last year, the United Nations General Assembly refused to include a discussion of the famine on its official session agenda.

A number of Ukrainian nationalist parties say that Russia, as the legal successor of the Soviet Union, should bear responsibility for the famine.
