March 3 (UPI) -- The U.S. embassy in Havana, Cuba, will permanently have a scaled-down staff, the State Department announced Friday.
The decision came more than six months after U.S. officials first divulged that more than a dozen embassy employees there were victims of alleged sonic attacks. In late September, the State Department temporarily removed all non-essential personnel from the embassy.
Starting Monday, the embassy will continue to operate with a similar emergency staffing level, the State Department said in a release Friday. The embassy's only remaining staffers will be there to "perform core diplomatic and consular functions," the department said.
The State Department has not indicated who carried out the attacks, but the Trump administration has expelled more than a dozen Cuban diplomats over the incidents.
"We still do not have definitive answers on the source or cause of the attacks, and an investigation into the attacks is ongoing," the State Department said Friday.
The State Department said in late January that 19 Americans who traveled to Cuba reported suffering symptoms -- including hearing loss, dizziness, fatigue and headaches -- consistent with the alleged sonic attacks at the embassy.
