KIEV, September 7 - RAPSI. Former Ukrainian Prime Minister Yulia Tymoshenko has challenged in court the authenticity of key prosecution evidence, the Russian Legal Information Agency (RAPSI) reports from the courtroom.

"I state that I did not sign the copy of the directives given to me for review, and it is not the original," she said on Wednesday in her testimony to a Kiev court.
The court has heard her case since late June.

The Ukrainian Prosecutor Generals Office has charged Tymoshenko with abuse of power due to her approval of a Russian gas contract in 2009 when she served as prime minister.

Tymoshenko was arrested on August 5.
