The head of the local Jewish Committee, Dr Seweryn Kahane, was fatally wounded by a GZI WP officer while telephoning the Kielce office of Public Security for help. A number of local priests attempted to enter the building but were stopped by militia officers, who vowed to control the situation. Following the initial murders inside the building, numerous Jews were driven outdoor by soldiers and later attacked with stones and clubs by civilians who crowded surrounding streets. By noon, the arrival of a large group of estimated about 600 to 1,000 workers from Ludwików steel mill, led by activists of Poland's ruling Polish Workers' Party (PPR, communist party), opened the next stage of the pogrom. Approximately 20 Jews were battered to death by the workers armed with iron rods and clubs. Some of the workers were members of the ORMO (volunteer reserve militia) and at least one possessed a handgun. Neither the military or security heads, including a Soviet army advisor, nor the local civic leaders, sought to prevent the aggression. A unit of Civic Militia cadets which also arrived at the scene did not intervene, but some of its members joined in the looting and violence which continued inside and outside the building. Among the slain Jews, nine had been shot dead, two were killed with bayonets, and the rest beaten or stoned to death. The dead included women and children. The mob also killed a Jewish nurse (Estera Proszowska), whom the attackers had mistaken for a Polish female attempting to aid the Jews. Two Jewish people not residing at Planty Street dwelling were also murdered on this day in separate incidents. Regina Fisz, her 3-week old child, and a male companion were abducted at their home at 15 Leonarda Street by a group of 4 men led by Civic Militia corporal Stefan Mazur. They were robbed and driven out of the city, where Regina and her baby were shot while allegedly trying to escape, while her friend did manage to escape. Three non-Jewish Poles were among the dead. Two uniformed state servicemen were killed in gunfire exchange, most likely shot by Jews defending themselves. The cause of death of the third man remains unexplained. Cessation of violence The pogrom ended at roughly 3:00 p.m. with the arrival of new security units from a nearby Public Security Academy, advanced by Colonel Stanisław Kupsza, and additional troops from Warsaw.
