The indictment, unsealed by Acting US Attorney Todd Blanche in Miami, includes charges of conspiracy to kill US nationals, destruction of an aircraft and four individual counts of murder against Castro and five other co-defendants. The maximum penalty for at least one of the charges is life imprisonment.

Blanche said a federal grand jury in Miami had issued the charges on April 23.

Speaking from Miami’s Freedom Tower – where more than 400,000 Cubans fleeing the island after the revolution were processed – Blanche said: “For nearly 30 years, the families of four murdered Americans waited for justice. The US and President Trump do not and will not forget its citizens … If you kill Americans, we will pursue you no matter the charge you hold and in this case, no matter how much time has passed.”
