While researching this piece I found this in Wilipedia about a similar panic in Ecuador, I remain sceptical but here it is:
In February 1949, Leonardo Paez and Eduardo Alcaraz produced a Spanish-language version of Welles’s 1938 script for Radio Quito in Quito, Ecuador. The broadcast set off panic in the city. Police and fire brigades rushed out of town to engage the supposed alien invasion force. After it was revealed that the broadcast was fiction, the panic transformed into a riot. Hundreds attacked Radio Quito and El Comercio, a local newspaper that had participated in the hoax by publishing false reports of unidentified objects in the skies above Ecuador in the days preceding the broadcast. The riot resulted in at least seven deaths, including those of Paez’s girlfriend and nephew. Paez moved to Venezuela after the incident.
