The demonstrations grew bigger and more heated than the 1999 student protests. Al Jazeera English described the 13 June situation as the "biggest unrest since the 1979 revolution." It also reported that protests seemed spontaneous without any formal organization. Two hundred people protested outside Iran's embassy in London on 13 June. Ynet has stated that "tens of thousands" protested on 13 June. Demonstrators are chanting phrases such as "Down with the dictator", "Death to the dictator", and "Give us our votes back". Mousavi has urged for calm and asked that his supporters refrain from acts of violence.
