US moving to indict former Cuban leader Raúl Castro: source

CBS News first reported on the potential charges.

Raúl Castro is the younger brother of longtime Cuban leader Fidel Castro, who died in 2016.

Castro is reportedly being indicted in connection with the downing of planes 30 years ago, U.S. officials familiar with the matter told CBS News.

The indictment, which would require approval from a grand jury, would center on Cuba's deadly 1996 shootdown of planes operated by the humanitarian group Brothers to the Rescue, according to the report.

Ratcliffe also stressed that the Trump administration was offering a genuine opportunity for cooperation and that Trump should be taken seriously, sources said.

"Cuba's got problems. We'll finish one first. I like to finish a job."
