CARACAS (Reuters) - Venezuela’s interior minister said on Thursday that authorities had arrested opposition leader Juan Guaido’s chief of staff for his involvement in an alleged “terrorist cell” that was planning attacks against high-level political figures.

Interior Minister Nestor Reverol, during an appearance on state television, showed an image of two rifles, which he called evidence collected against Roberto Marrero.

The opposition had said earlier that intelligence agents had planted weapons in Marrero’s house during a pre-dawn raid, a move by President Nicolas Maduro that the Trump administration said would “not go unanswered.”
