Former Ukrainian Ambassador to Russia, now Ukraine's Permanent Representative to the United Nations Volodymyr Yelchenko is testifying in Kyiv's Obolonsky district court as a witness in the Yanukovych's treason case.

The questioning began at about 11:30 Kyiv time, an UNIAN correspondent reports.

Yelchenko noted that at the end of February 2014, he had been reporting almost daily to the acting president, prime minister and foreign minister.

"As Ukraine's ambassador to Russia, I proceeded from doing everything possible to return our bilateral relations to normal, despite those tragic events," the diplomat said.

The only source of communication was our Embassy in Moscow, but we did not receive any replies to the embassy's requests to explain what Russia was doing in Crimea. In fact, they were ignored by the Russian Foreign Ministry," Yelchenko said.

Yelchenko served as the Ambassador of Ukraine to the Russian Federation from July 2010 to December 2015.
