Ukrainian President Viktor Yanukovich and Foreign Minister Avigdor Lieberman presided on Monday over a ceremony in Kiev to mark the 70th anniversary of the massacre at Babi Yar. Some 33,771 Jews were murdered there on the last two days of September in 1941.
Hundreds of descendants of the victims, as well as survivors, participated in the ceremony.

Opinion: Uman, yes. So why not Babi Yar?
"It is difficult to fully comprehend the events that occurred in Babi Yar. It is difficult to find the words to express all the depth of our condolences and sorrow," Yanukovich said at the ceremony, according to a speech released to the French news agency AFP before the event. "More and more, time is increasing our distance from these horrible events. But the memory is alive."
The Jews had assembled at the Babi Yar ravine in 1941, shortly after the Nazi forces pushed the Soviet authorities out of Kiev, because they believed they were being resettled.
Between September 1941 and 1943, some 150,000 people were executed by Nazi troops in wooded areas on the outskirts of Kiev. Most were Jews, but the total also included ethnic Ukrainians, Russians, Poles and Roma, or gypsies.
