Venezuelan soldiers blew up two pedestrian bridges across the Colombia-Venezuelan border, Colombia's government said Thursday, according to Reuters.

It is the latest incident in what is an already-strained relationship.

Colombian Defense Minister Gabriel Silva said explosives were used to blow up the bridges in what he called a violation of international law, Reuters reported.

"Uniformed men, apparently from the Venezuelan army, arrived in trucks on the Venezuelan side at two pedestrian bridges that link communities on both sides ... and then proceeded to dynamite them," Silva said, according to Reuters.
