Identity of the victim(s): large crowd of peaceful protesters

Identity of the perpetrator(s): undefined

Daytime. Square full of peaceful protesters. At some point, people started shouting very loudly and running (away from some sort of explosion, possibly a flash grenade used to disperse the crowd). We cannot clearly see who tossed the grenade. Then, there was a second explosion with a lot more smoke coming out of it. The perpetrators probably used a gas grenade.
