The Ukrainian Security Service's (SBU) main investigations department expects that the international investigative team probing the Malaysia Airlines Flight 17 crash in the Donetsk region in July 2014 will make a joint coordinated decision by the end of 2015 on determining the guilt of all those responsible for the crash and qualifying their actions.

"As the investigation is being pursued by a joint investigative team, a decision on holding people criminally liable will be made based on the evaluation of the evidence collected by representatives of four states. This work is continuing now, and I think a coordinated decision will be made by the end of the year regarding the individuals whose responsibility for committing the crime can be confirmed by the evidence collected, and regarding the qualification of their actions," SBU main investigations department deputy chief Vitaliy Mayakov said at a news briefing in Kyiv on Thursday.

A decision on qualifying these individuals' actions will be made at a joint conference of investigators from the states involved in the investigation, he said.

"A decision regarding the qualification of everyone's actions will be made based on the results of a joint conference of all members and chiefs of the international investigative team, because the proceedings are under way in all four countries, including Malaysia [and also in Ukraine, Belgium, and the Netherlands]," Mayakov said.

"The international investigative team has collected evidence that gives grounds to hold concrete individuals criminally liable, and the next stage is notifying them of being suspected or indicting them. This issue is under consideration at the moment," he said.
