Martial law was declared on May 20, 1989. Late on June 3 and early on the morning of June 4, a date now synonymous with the movement in the Chinese language, military units were called from neighboring provinces and brought into Beijing. Armed force was used to clear demonstrators from the streets. Official PRC estimates place the number of deaths at between two and three hundred, whilst groups such as the Red Cross believe the number to be in the two to three thousand range.
