Venezuela: Maduro brandishes sword and vows to defy any US attempt to overthrow his government

Venezuelan President Nicolas Maduro has vowed to defy any US attempt to overthrow his government - telling crowds that "failure is not an option".

The 63-year-old brandished a sword as he addressed supporters during a march in Caracas, against a backdrop of growing tensions with Donald Trump's administration.

Dressed in camouflage fatigues, Mr Maduro said: "We must be ready to defend every inch of this blessed land from imperialist threat or aggression, no matter where it comes from."
