In a statement just issued, Georgia's Prime Minister Giorgi Kvirikashvili stated "What has happened this evening in Tbilisi is not only sabotage against the state, but also a provocation plotted by Georgia's enemies to instigate instability ahead of the elections. An investigation has already been launched and all necessary measures are being taken to arrest those responsible," he added.
"This grave crime can only be in the interest of a force, which is unable to make its peace with the free and peaceful electoral environment in our country. I want to tell plotters and executors of this provocation - you will definitely be held accountable to the fullest extent of the law."
"No immunity or foreign citizenship can protect those responsible - everyone will be held accountable," the PM said. "Once and for all, we will put an end to endangering people's lives for the purpose of political goals," he added.
Meanwhile reports from Tbilisi Health Ministry say that of the four passers by who were injured by the explosion, one is in serious condition.
