Maduro also described the U.S. actions as a "grave military aggression" and violation of the United Nations charter, adding that it threatened peace across Latin America and the Caribbean, The Miami Herald reported. 

The U.S. has been carrying out a military campaign against alleged drug-trafficking boats in the Caribbean and Eastern Pacific in recent months. 

Maduro’s government cast the U.S. strikes on Saturday as part of a larger American effort to seize Venezuela’s oil and mineral reserves, according to The Miami Herald. 

The newspaper reported that state TV broadcast images of Venezuelan soldiers deploying to strategic infrastructure and officials holding emergency meetings. 

As part of Maduro’s response, he signed a decree that declared a nationwide state of "external disturbance," which gives his government sweeping powers during emergencies, including mobilizing security forces and limiting certain civil liberties, The Miami Herald added.
