The explosions in the center of Dnipropetrovsk on Friday are likely to have been caused by caseless explosive devices.
The conclusion was drawn by security experts polled by Interfax.
In their opinion, the nature of injuries resulting from the blasts permit the conclusion that the bombs had not been filled with destructive agents and the traumas are most likely to have been caused by fragments of trash bins and other objects.
Experts have not established the exact type or power of explosive devices yet.
