Bulgarian umbrella

Such an umbrella was used in and named for the assassination of the Bulgarian dissident writer Georgi Markov on 7 September 1978^[1] (the birthday of the Bulgarian State Council chairman Todor Zhivkov, who had often been the target of Georgi Markov's criticism) on Waterloo Bridge in London. Markov died four days later.

It was also allegedly used in the failed assassination attempt against the Bulgarian dissident journalist Vladimir Kostov the same year in the Paris Métro. The poison used in both cases was ricin. Both assassination attempts are believed to have been organized by the Bulgarian Secret Service of the time of the Cold War with the assistance of the KGB.^[2]

Such an umbrella was intended to be used in the assassination of Pallo Jordan and Ronnie Kasrils by the South African Civil Cooperation Bureau death squad.^[3]
