Andrej Hunko, a member of the Left Party parliamentary group in the Bundestag and a member of the Parliamentary Assembly of the Council of Europe, told reporters during a press conference in Moscow that he was "concerned with the issue of the mass killing in Odessa since no real investigation was conducted."
The lawmaker added that he was in close contact with the relatives of the victims.
On May 2, clashes in Odessa broke out between pro-federalization activists on one side and fans of the Odessa and Kharkiv football teams on the other, later joined by Euromaidan activists.
Pro-Kiev radicals, including the Right Sector ultranationalist group, blocked the anti-government protesters in the Trade Union House and set the building on fire by hurling Molotov cocktails inside.
At least 48 people died and more than 200 were injured in the blaze and clashes.
"As far as I know, the Council of Europe plans to monitor the situation in this respect," Hunko noted.
Last week, Russian Foreign Minister Sergei Lavrov praised the Council of Europe for creating a special group tasked with probing tragic events in Kiev and Odesa.
