Uniformed men destroyed with dynamite two bridges near Ragonvalia, Colombia, Reuters reported Nov. 19, citing Colombian Defense Minister Gabriel Silva, who said the men were “apparently Venezuelan soldiers.” Ragonvalia Mayor Elmer Gamboa Tulante had previously said that approximately 40 Venezuelan soldiers had attacked three bridges, placing explosive charges on two suspension bridges and a small vehicle bridge near the Venezuelan border, according to Terra.
