VENEZUELAN President Nicolas Maduro has accused the Organisation of American States (OAS) of acting as colonialists and promoting regime change on behalf of the US across the region.

He was speaking after Monday’s session of the 35-member OAS in Washington when he warned that the US was using the international bloc to attack the people of Latin America and anti-imperialist governments.

"The OAS is a useless organism that suffered an involution and has become again a ministry of colonies of the American empire against revolutionary movements, against progressive peoples and independent anti-imperialist governments,” Mr Maduro blasted.
