The US government has expelled 15 Cuban diplomats from the country’s embassy in Washington, accusing Havana of failing to protect US staff on the communist-ruled island.
The Cuban ambassador has been told his diplomats have seven days to leave.
The Trump administration’s move marks a further deterioration in relations following President Obama’s policy aimed at closer ties.
“This is not a punishment. Cuba we are not going to say is responsible for these attacks. Let me be clear about that,ok?” said US State Department spokeswoman Heather Nauert. “Cuba has a responsibility under the Vienna Convention to ensure the safety and security of our diplomats and our diplomatic families.”
Last week the US said it was sharply reducing its diplomatic presence in Cuba, saying more than 20 staff had suffered hearing loss, dizziness and fatigue in a series of mysterious attacks.
