The Trump administration will expel almost two-thirds of Cuba's diplomatic corps in the U.S. after a series of mysterious "sonic" attacks that have affected at least 25 American personnel in Havana, according to a report.

"Cuba is not upholding its commitments of the Vienna convention, of protecting diplomats," a U.S. official told McClatchy.

The State Department has not censured Cuba over the acoustic attacks by the still unknown device or weapon, per the news organization. But it has withdrawn many of its own staff from the country and issued a travel warning after receiving several complaints of hearing loss and "cognitive issues" from diplomats and their families.

Raul Castro's regime has repeatedly denied being involved in the incidents, which started in November but weren't publicized until August.

"Cuba has never perpetrated nor will it ever perpetrate actions of this sort," Cuban Foreign Minister Bruno Rodriguez Parrilla said in an address at a United Nations event in September. "Cuba has never allowed nor will it ever allow its territory to be used by third parties with that purpose."
