"Official sources have confirmed the information," Nikoloz Natbiladze said.
At least thirteen people were killed and 11 wounded when a gunman opened fire at the State Oil Academy in Azerbaijan's capital on Thursday morning, according to the country's health ministry.
Azerbaijan's Interior Ministry named the shooter as Georgian national Farda Gadyrov, born in 1980 and of Azerbaijani origin.
Gadyrov was reported to have killed a security guard and cleaner after entering the academy. He then continued shooting indiscriminately at students and staff with a Makarov pistol while going up a staircase.
Azerbaijan's ANS television channel said the gunman had killed 17 and wounded 13, including Azerbaijani, Turkish and Syrian nationals, before killing himself.
The academy is a major international center for the training of oil industry specialists. Former students include Soviet-era secret police head Lavrenty Beria and Vagit Alekperov, president of Russia's largest independent oil producer, LUKoil.
A probe into the incident has been launched under the supervision of Azerbaijani President Ilkham Aliyev, who has already conveyed his condolences to the families of those people killed in the attack.
