Venezuela crisis: Maduro closing border with Brazil

Venezuelan President Nicolás Maduro has announced the closure of the border with Brazil as a row over foreign humanitarian aid continues.

The embattled leftist leader went on TV to say that he was also considering shutting the border with Colombia to stop the opposition bringing in relief.

He denies any crisis and calls the aid delivery plans a US-orchestrated show.

Opposition leader Juan Guaidó is leading a convoy from the capital, Caracas, to the Colombian border.

Later on Friday, a huge concert will be held on the Colombian side of the border to raise money for Venezuela.

At the same time, Mr Maduro's government will hold its own event, reportedly just some 300 metres away.

Mr Guaidó declared himself interim leader during anti-government protests last month and is recognised by dozens of foreign states, including the US and most Latin American countries.
