Venezuela's Supreme Court barred opposition leader Juan Guaido from leaving the country Tuesday, a move certain to heighten tensions as the man challenging President Nicolas Maduro's claim to the presidency presses forward with establishing a transitional government and the US warned of "serious consequences" if he is harmed.
The government-stacked high court announced the order just hours after chief prosecutor Tarek William Saab announced that he was opening a criminal investigation into Guaido's anti-government activities and requested that restrictions be placed on his movements abroad.
The court also approved Saab's request that all of Guaido's financial assets be frozen.
US national security adviser John Bolton issued a warning to the Maduro government earlier in the day urging them not to harm Guaido, the head of the opposition-controlled congress who has been recognized by the Trump administration and two dozen other nations as Venezuela's rightful president. "Let me reiterate.
There will be serious consequences for those who attempt to subvert democracy and harm Guaido," Bolton said on Twitter.
The Supreme Court's order comes as tensions between the U.S. and Venezuela reach a new high, with Maduro accusing the Trump administration of staging a coup against his presidency and Guaido seeking to consolidate an interim government under his own leadership.
Guaido has thus far managed to avoid arrest, and the Supreme Court did not strip him of his legislative immunity, though the new investigation may signal that Maduro's socialist government is moving to take a more punitive approach.
Speaking earlier outside the National Assembly, Guaido said he is aware of personal risks, but added, "Venezuela is set on change, and the world is clearly conscious of what's happening."
Pompeo said the certification would "help Venezuela's legitimate government safeguard those assets for the benefit of the Venezuelan people."
Violent street demonstrations erupted last week after Guaido during a huge opposition rally in Caracas declared that he had assumed presidential powers under the constitution and planned to hold fresh elections to end Maduro's "dictatorship."
