WASHINGTON (Reuters) – The Trump administration on Monday announced it was returning Cuba to the U.S. list of state sponsors of terrorism.

Secretary of State Mike Pompeo said Cuba was being blacklisted for “repeatedly providing support for acts of international terrorism” by harboring U.S. fugitives as well as Colombian rebel leaders.

Pompeo also cited Communist-ruled Cuba’s security support for Venezuelan President Nicolas Maduro, which he said had allowed the socialist leader to create “a permissive environment for international terrorists to live and thrive within Venezuela.”

“With this action, we will once again hold Cuba’s government accountable and send a clear message: the Castro regime must end its support for international terrorism and subversion of U.S. justice,” Pompeo said in a statement.

The terrorism list decision followed months of legal review, with some administration experts questioning whether it was justified, a person familiar with the matter told Reuters, speaking on condition of anonymity.

Trump has clamped down on Cuba since coming to power in 2017, tightening restrictions on U.S. travel and remittances to Cuba, and imposing sanctions on shipments of Venezuelan oil to the island.

Trump’s hardline Cuba policy was popular among the large Cuban-American population in South Florida.

Syria, Iran and North Korea are other countries on the list.
