Venezuela has arrested three Americans, two Spaniards, and a Czech citizen over an alleged CIA plot to assassinate President Maduro.

The arrests were announced by Diosdado Cabello, the nation’s interior minister. Cabello said the foreign citizens were part of a CIA-led plot to overthrow the Venezuelan government and kill several members of its leadership.

The interior minister showed images of rifles that he said were confiscated from some of the plotters of the plan.
