The US is withdrawing more than half of its staff at its embassy in Cuba in response to mysterious attacks which left its diplomats unwell.
Washington is also warning Americans not to visit the country because some attacks occurred in hotels.
At least 21 staff reported health problems ranging from mild brain trauma and deafness to dizziness and nausea.
Describing the US decision as “hasty”, Cuba said it would affect bilateral ties but co-operation would continue.
US Secretary of State Rex Tillerson said the two countries would continue to co-operate in investigating the attacks and said diplomatic ties would be maintained.
Earlier reports suggested that sonic attacks were to blame. Cuba denies any involvement.
At least two Canadians were also affected. -bbc.com
