On 18 December 1989, Ceaușescu departed for a state visit to Iran, leaving the duty of crushing the Timișoara revolt to his subordinates and his wife. Upon his return to Romania on the evening of 20 December, the situation became even more tense, and he gave a televised speech from the TV studio inside the Central Committee Building (CC Building), in which he spoke about the events at Timișoara in terms of an "interference of foreign forces in Romania's internal affairs" and an "external aggression on Romania's sovereignty."
