US, Venezuela tensions soar as Trump, Maduro spar

Tensions flared once again Wednesday between the United States and Venezuela as Donald Trump called for the release of a jailed foe of President Nicolas Maduro, who warned the new US leader not to provoke him.

Diplomatic rows have become somewhat commonplace over the past 20 years between Venezuela's leftist leaders and Washington, the "imperialist" power they love to hate. They have not traded ambassadors since 2010.

But with the Republican Trump only in office since January 20, any hope of some kind of breakthrough appeared to be quickly vanishing.

"Venezuela should allow Leopoldo Lopez, a political prisoner & husband of @liliantintori (just met w/ @marcorubio) out of prison immediately," Trump tweeted.

The post included a picture of Trump, Vice President Mike Pence, Lopez's wife Lilian Tintori and Florida Senator Marco Rubio at the White House. Trump's public schedule had only mentioned a dinner with Rubio.

Lopez, the founder of Popular Will, one of the most hardline of the parties opposing Maduro, is serving a 14-year prison term on charges of inciting unrest at anti-government protests that left 43 people dead in early 2014.

Ties had already been rattled on Monday, when the US Treasury imposed sanctions on Maduro's powerful Vice President Tareck El Aissami and a businessman, whom US authorities accuse of being involved in drug trafficking.

The US Treasury department froze the US assets of El Aissami and the businessman, Samark Jose Lopez Bello, and banned US nationals from doing business with them.
