“This barbaric crime cannot go unpunished. Its organizers and implementers must answer to what was done. What has happened once again proves the necessity of uniting all governments in the fight with international terrorism,” the Foreign Ministry said in a statement.
Moscow expresses condolences over the deadly explosion in Ankara on Wednesday, it added.
The blast targeted a bus with military personnel on Wednesday as they were waiting at traffic lights in the Turkish capital some 300 meters (984 miles) from the country’s parliament building.
According to media reports, the bomber was a Syrian national who had entered Turkey with refugees.
Russia has repeatedly called for tighter anti-terror cooperation since the onset of the Islamist insurgency in the Middle East.
