US planning to criminally indict ex-Cuban leader Raúl Castro

He added: "But [Cubans] need help, as you know. And you talk about a declining country. They are really a nation, a country in decline."Trump has issued an oil blockade against Cuba, which has exacerbated fuel shortages. This week the island's energy minister acknowledged that Cuba has, in essence, run out of fuel oil.Potential charges against Raúl Castro were unclear, but officials said the investigation centred on an attack on two small planes, which happened on 24 February 1996 while Fidel was president and Raúl was armed forces minister.Four people aboard were killed in the incident.Brothers to the Rescue, a Cuban exile group that searched for rafts carrying migrants from Cuba to the US, had previously dropped anti-Castro leaflets near the Cuban coast.The Cuban government - including Fidel Castro, who died in 2016 - said Brothers to the Rescue had repeatedly violated Cuban airspace, although the International Civil Aviation Organization found the attack took place over international waters.AFP via Getty ImagesRaúl Castro took over leading Cuba after his brother, Fidel Castro (left). In March, the attorney general in Florida announced in a news conference that the state was reopening an investigation into Raúl Castro's alleged role in the incident. Florida's Governor Ron DeSantis praised the possible criminal charges on Friday, calling them "long overdue".Cuba has not officially commented on the reports of an indictment, but Foreign Minister Bruno Rodriguez struck a defiant tone on Friday."Despite the [US] embargo, sanctions and threats of the use of force, Cuba continues on a path of sovereignty towards its socialist development," he said, according to Reuters news agency.In order for charges to be filed, prosecutors would have to convince a grand jury, made up of members of the public, that probable cause exists to believe a crime has been committed.Acting US Attorney General Todd Blanche, who leads the US justice department, has declined to confirm reports of an impending indictment."If and when there's a time to talk about about that, we will, obviously," Blanche told Fox News.Trump has said the US wants to change Cuba's communist leadership. He told crowds at a recent rally that the US would be "taking over" the Caribbean island nation, which lies 145km (90 miles) from the US state of Florida. CIACIA Director John Ratcliffe in HavanaOn Thursday, CIA director John Ratcliffe met his Cuban counterpart at the interior ministry in Havana. Raúl Rodríguez Castro, grandson of Raúl Castro, was at the meeting.A CIA official told the BBC's US partner CBS that Washington was prepared to engage on economic and security issues, "but only if Cuba makes fundamental changes".A Cuban statement said the meeting was an attempt to improve dialogue and that Havana was not a threat to US national security. It came after American officials renewed an offer of $100m (£74m) of aid to ease the effects of its oil blockade.Washington has focused more on Cuba in recent months after the US indicted Venezuelan leader Nicolás Maduro in January then removed him from power in an overnight operation. Analysts say any similar attempt by US special forces to arrest Castro could meet stiff opposition in Cuba, particularly among government loyalists.William LeoGrande, professor of Latin American politics at the American University in Washington, told the BBC the potential indictment was "one more element of the pressure campaign" that Trump has kept up since returning to office last year.
