The bomb to blow up the colonel flew to the Leningrad region in a hot air balloon from the Baltic states, Fontanka writes. An unknown person collected the explosives and hid them in a cache, from where a 31-year-old resident of St. Petersburg took the charge. The man planted a bomb under the car and after a few hours flew to Istanbul. When the explosion occurred, the alleged perpetrator was already on his way to Chisinau.
