On October 25, 1956, armed forces began firing on demonstrators at parliament from adjacent rooftops, murdering over 100 and wounding several hundred more.
The demonstrators became incensed when a speaker from the foundation organizing the commemoration said the names of the killers were not known.
"We know who the murders were, and their sons are sitting in parliament," they roared. Members of this small but active group have been staging protests in and around parliament for over a year, alternately demanding the resignation of the prime minister, the cabinet, and parliament.
In all, some 200 people gathered for the commemoration and counter-demonstration.
