Twitter has suspended several accounts run by the Cuban government, including accounts of state-run media and officials, including the daughter of Communist Party leader Raul Castro.
The social media giant cited a violation of his policies.
The move came at a time when President Miguel Diaz Canel made a statement about the possible shortage of fuel.
The pro-government press syndicate in Cuba condemned the comment as “collective censorship”.
“What is new here is the enormous scope of this act of cyber warfare, clearly planned, aimed at restricting the freedom of expression of Cuban institutions and citizens and silencing the leaders of the revolution,” the union said in a statement.
The suspension began before President Diaz Canel’s announcement on state television on Wednesday and continued the following morning.
They include the account of the television show, Mesa Redonda, in which Mr. Diaz Canel appeared; the state-run Granma Digital newspaper; the state radio station Radio Rebelde;
A Twitter spokesman did not provide specific examples of where his rules were broken.
But he said the company’s platform manipulation policies prohibit users from inflating or disabling conversations using multiple accounts.
The company added that the relevant account holders were contacted and informed of the reasons for the suspension.
Twitter Twitter CEO Jack Dorsey and co-founder visited Cuba recently and State Department officials have publicly asked for clarification, the BBC’s Will Grant in Havana said.
In his televised address, Mr. Diaz Canel warned of fuel supply problems in the coming weeks.
He said the distribution of fuel, especially diesel, was badly hit by US sanctions against Venezuela – Cuba’s main oil supplier.
He said a power outage is likely next week, suggesting that people should work from home
