The United States on Wednesday accused its adversaries Venezuela and Cuba of fomenting strife in South America, where a number of countries have seen major protests.

Elliott Abrams, who leads the US effort to topple Venezuela's leftist leader Nicolas Maduro, said the two governments have used social media and other means to stir up unrest.

"There is evidence beginning to build about an effort by the regimes in Cuba and Venezuela to exacerbate the problems in South America," he told reporters.

Abrams pointed to US ally Colombia's recent expulsion of 59 Venezuelans for taking part in mass demonstrations against the unpopular conservative president, Ivan Duque.

He also cited allegations, denied by Havana, that Cubans financed protests against the right-leaning interim leader in Bolivia, where longtime leftist president Evo Morales quit after disputed elections.

US officials have previously also alleged Venezuelan involvement in demonstrations that have rocked Ecuador and Chile.

Despite the turbulence in the region, Maduro remains in power even though most Western and Latin American nations consider him illegitimate after wide reports of irregularities in elections last year.

The United States in January launched a campaign of sanctions and other pressure to topple Maduro and back Juan Guaido, the head of the opposition-led National Assembly whom Washington considers interim president.

Abrams said the United States would not change course and still expected success.

"No, we don't have a Plan B. We have a Plan A. We think it will work," he said.

"There can be no solution to the terrible problems faced daily by Venezuelans while the Maduro regime is in power, because the Maduro regime created those problems and is exacerbating them," he said.

Maduro presides over a crumbling, state-directed economy that has seen eye-popping levels of inflation and triggered the exodus of millions of Venezuelans who cannot find basic necessities.
