Ukrainians have marked the 75th anniversary of the Babi Yar massacre, one of the most infamous mass slaughters of World War II.

Babi Yar, a ravine in the Ukrainian capital, is where nearly 34,000 Jews were killed within 48 hours in 1941, when the city was under Nazi occupation. The killing was carried out by SS troops along with local collaborators.

President Petro Poroshenko visited the Babi Yar monument on Thursday in a small commemoration that included people laying flowers. A larger ceremony was scheduled for the evening.

Poroshenko tweeted that "we Ukrainians very well understand the grief of the Jews and take it as our own."
