Cuba: No clue on cause of diplomat sickness
Cuba's top diplomat has says his country has unearthed no information about who or what caused a mysterious series of health incidents that affected US and Canadian diplomats in Havana.
Foreign minister Bruno Rodriguez Parrilla told the United Nations General Assembly on Friday that early results from its investigation had "found no evidence whatsoever that could confirm the causes or the origin" of the problems.
At least 21 Americans and several Canadians in Havana's diplomatic community have suffered from symptoms believed to have come from some sort of sonic attack.
The symptoms include hearing loss and brain damage.
US secretary of state Rex Tillerson has described the incidents as "health attacks".
Cuba has denied any involvement or knowledge of them and Mr Rodriguez reiterated that denial on Friday.
