KYIV, Sept 29 - Ukraine marked the 80th anniversary on Wednesday of the mass shooting of civilians at the wooded ravine of Babyn Yar in Nazi-occupied Kyiv, one of the biggest single massacres of Jews during the Holocaust, Reuters reported.

Nazi troops at Babyn Yar gunned down nearly 34,000 Jewish men, women and children on Sept. 29-30, 1941. Over the two years that followed, around 150,000 people in total, mostly Jews but also including Ukrainians, Russians, Poles and Roma, were killed there.
