The attack caused a wave of violent repressions organized by the Military Union with the government's tacit approval. During the following two weeks, approximately 450 people were executed without trial, including poet Geo Milev and journalist Yosif Herbst. (A mass grave of those killed in 1925 was discovered in the 1950s during the construction of a dam, and Milev's corpse was identified by his glass eye - he had lost an eye in World War I.)
