Talking to journalists the next day, he said that the device was hurled to hit a car carrying Ukrainian Armed Forces servicemen. It bounced back from the side of the car, exploded and seriously wounded several civilians who happened to be relatives of Hero of Ukraine sniper Valeriy Chybineyev.
"Bomb experts are working now, they will prove a clear classification of the device. Further legal classification of the crime depends on this," he said.
He expects the experts' conclusions by Monday, 28 August.
The case is being investigated as attempted murder.
