interesting read, same situation as we see in iran now
As he was addressing the crowd from the balcony of the Central Committee building, sudden movement came from the outskirts of the massed assembly, as did the sound of (what various sources have reported as) fireworks, bombs, or guns, which together caused the assembly to break into chaos. Initially frightened, the crowds tried to disperse. Bullhorns then began to spread the news that the Securitate was firing on the crowd and that a "revolution" was unfolding. This persuaded people in the assembly to join in. The rally turned into a protest demonstration.
The entire speech was being broadcast live around Romania, and it is estimated that perhaps 76% of the nation was watching. Censors attempted to cut the live video feed, and replace it with communist propaganda songs and video praising the Ceauşescu regime, but parts of the riots had already been broadcast and most of the Romanian people realized that something unusual was in progress.
Ceauşescu and his wife, as well as other officials and CPEx members, panicked, and Ceauşescu went into hiding inside the building.
The reaction of the Ceauşescu couple on the balcony is memorable: They staged futile attempts to regain control over the uprising crowd using phone conversation formulas such as "Alo, Alo" ("Hello, Hello"), Ceauşescu's wife "advised" him how to contain the situation "Vorbeşte-le, vorbeşte-le" ("Talk to them, talk to them"), and they urged the crowd "Staţi liniştiţi la locurile voastre" ("Stay quiet in your places"). In the end Ceauşescu allowed himself to be directed into the Central Committee building by his underlings.
The jeers and whistles soon erupted into riot; the crowd took to the streets, placing the capital, like Timişoara, in turmoil. Members of the crowd spontaneously began shouting anti-communist and anti-Ceauşescu slogans, which spread and became chants: "Jos dictatorul!" ("Down with the dictator"), "Moarte criminalului!" ("Death to the murderer"), "Noi suntem poporul, jos cu dictatorul!" ("We are the People, down with the dictator"), "Ceauşescu cine eşti?/Criminal din Scorniceşti" ("Ceauşescu, who are you? A murderer from Scorniceşti"). Protesters eventually flooded the downtown area, from Piaţa Kogălniceanu to Piaţa Unirii, Piaţa Rosetti, and Piaţa Romană. In one notable scene from the event, a young man waved a tricolour with the Communist coat of arms torn out of its center, while perched on the statue of Mihai Viteazul on Boulevard Mihail Kogălniceanu in the University Square.
As the hours passed, many more people took to the streets. Soon the protesters — unarmed and unorganized — were confronted by soldiers, tanks, TABs, USLA troops (Unitatea Specială pentru Lupta Antiteroristă, anti-terrorist special squads), and armed plain-clothes Securitate officers. The crowd was soon being shot at from various buildings, side streets, and tanks. There were many casualties, including deaths, as victims were shot, clubbed to death, stabbed, and crushed by armored vehicles (one TAB drove into the crowd around the InterContinental Hotel, crushing people — a French journalist, Jean Louis Calderon, was killed; a street near University Square was later named after him, as well as a high school in Timişoara). Firefighters hit the demonstrators with powerful water jets and the police continued to beat and arrest people. Protesters managed to build a defensible barricade in front of Dunărea ("Danube") restaurant, which stood until after midnight, but was finally torn apart by government forces. Intense continuous shooting continued until after 3:00 a.m., by which time the survivors had fled the streets.
