A day after Bolivia suspended diplomatic relations with Cuba, Havana accused its interim government of having sought to sabotage bilateral ties ever since it took power last year, partly under pressure from the Trump administration.

Cuba was a key ally of Bolivia's former President Evo Morales – who resigned amid a political crisis and protests in November – and has supported Morales's assertion that he was toppled in a foreign-backed "coup".

Bolivia's interim President Jeanine Anez, meanwhile, has tried to align the country more closely with U.S. President Donald Trump's administration, which is cranking up sanctions on Cuba.

"The acting authorities unfurled a ferocious campaign of lies against Cuba...in particular against the Cuban medical cooperation, inciting violence against our staff," the Cuban foreign ministry said in a statement on Saturday.

"It is not casual that the facts described here coincide with a brutal, politically-motivated U.S. campaign against the international medical cooperation Cuba provides to dozens of countries."

Cuba's foreign ministry also said U.S. officials had, since the departure of Morales, "applied pressure on Bolivia to impose a deterioration in relations with Cuba."

The U.S. State Department was not immediately available for comment.
