"The Malaysian Boeing crash near Donetsk took the lives of almost 300 people. There has been no effective or impartial investigation into this tragedy as of yet, which is evidently in violation of UN Security Council's Resolution 2166 and the rules of the International Civil Aviation Organization, ICAO," Dolgov said during a conference at the Rossiya Segodnya press center.
The Australia-initiated UN resolution was adopted on July 21 in the wake of the plane crash to back "efforts to establish a full, thorough and independent international investigation into the incident in accordance with international civil aviation guidelines".
The Russian ombudsman hit out against the sluggish pace of the investigation, saying those "who are not interested in establishing the truth have effectively slammed the brakes on" the probe.
According to a preliminary report issued by the Dutch Safety Board in September, the plane most likely broke up in mid-air because of structural damage from a large number of high-energy objects that penetrated the aircraft from the outside.
Kiev has accused independence supporters in eastern Ukraine of shooting the plane down, while local militia leaders say that they do not have weapons capable of striking an aircraft flying at 32,000 feet.
