Venezuela's President Nicolas Maduro is ordering the border with Brazil closed as opposition leaders plan to bring in foreign humanitarian aid from neighboring nations.

Maduro said on state television Thursday he's also considering a closure of Venezuela's border with Colombia.

Opposition leaders say they plan to mount caravans to bring aid into Venezuela from Colombia and Brazil. Maduro says the aid meant to undermine and overthrow him and says Venezuela needs no such shipments.
