In the autumn of 1919, the Armenian Revolutionary Federation (ARF), part of the Armenian national liberation movement, ruled to punish the executors of the Armenian Genocide. Under Operation Nemesis, Aram Yerganian and Arshavir Shirakian were given the task to assassinate both Cemal Azmi and Shakir who were in Berlin. On April 17, 1922, Shirakian and Yerganian encountered Azmi and Shakir who were walking with their families at the Uhlandstrasse street.[6] Shirakian managed to kill only Azmi and wound Shakir.
