The article mentions that The Guernica Group has "campaigned for the prosecution in Spain" of those behind the murder of six Jesuit priests, their housekeeper, and the housekeeper’s daughter on 16 November 1989 by the Atlacatl Battalion of the Salvadoran Military. Relevantly, as recently announced, on 8 June 2020, the Spanish National Court will begin the trial of former Colonel and Vice-Minister of Public Security, Inocente Orlando Montano, for his alleged involvement as one of the key decision-makers behind the Jesuit killing.
The journalist contacted Almudena Bernabéu -co-founder and Executive Director of The Guernica Centre for International Justice-, who speculated that "Spanish arrest warrants may have figured in the State Department decision after one of the men named in the warrants applied for a U.S. visa".
