Explosives
Fake Stielhandgranate

Note:real explosions are seen,but they were caused by(most likely) petards, and not hand grenades.
No. 15 Hand Grenade "Ball"
During the storm, real explosions tear down the door of the house. At a closer look, some rounded grenades are seen. They were, most probably, british No. 15 Hand Grenade "Ball"'s as they had fuses, and a similar shape.
