Speaking at a press conference on Friday, the institute's head Alexander Dobroyer referred to the poll, which showed that a total of 48 percent of Odessa's citizens accuse the Ukrainian authorities of starting the war.
The figure includes about 25 percent of respondents who blame the current power and more than 20 percent who point the finger at the former authorities.
In addition, 12.2 percent insist that the United States is to blame for the hostilities, while 6.7 percent lay the blame on the European Union.
Notably, only 7.7 percent of respondents accused the governments of the self-proclaimed Donetsk and Lugansk Republics of initiating the conflict.
Ukraine has been mired in a civil war since April 2014, when Kiev launched a military operation against militias in the country’s southeast.
Moscow’s relations with Kiev deteriorated greatly amid the Ukrainian crisis, with Kiev accusing Russia of meddling in the conflict. Russia has repeatedly denied these allegations.
