 During the summer of 1942, using names supplied by Mihailović, lists of individual Nedić and Ljotić supporters to be assassinated or threatened were broadcast over BBC radio during news programming in Serbo-Croatian.Once the British discovered this, the broadcasts were halted, although this did not prevent the Chetniks from continuing to carry out assassinations.To gather intelligence, official intelligence missions of the western Allies were sent into both the Partisans and the Chetniks.
