The Justice Department is poised to announce charges against Raul Castro, sources close to the matter revealed to ABC News. The charges are expected to include allegations of murder stemming from the 1990s downing of two planes carrying humanitarian aid. These incidents resulted in the deaths of three American pilots.

The press conference to announce these charges is scheduled for this afternoon. The events in question date back to the 1990s, a period marked by significant political tension and humanitarian crises in the region.

Sources familiar with the investigation indicated that the charges specifically relate to the shooting down of aircraft that were attempting to deliver aid to migrants. The loss of life, including three American pilots, has been a focal point of the Justice Department's inquiry.

This development signals a significant move by the U.S. Justice Department to hold a high-profile international figure accountable for actions that led to the deaths of American citizens. The implications of such charges could extend to diplomatic relations and international law.

Raul Castro, who previously served as the President of Cuba and is the brother of Fidel Castro, has long been a figure of international scrutiny. The specific details surrounding his alleged involvement in the order to shoot down the planes are expected to be elaborated upon during the official announcement.

The 1990s saw Cuba facing severe economic hardship, and the government's response to perceived threats, including migration and foreign interference, was often stringent. The downing of the planes by Cuban forces was a controversial event that drew international condemnation at the time.

Families of the victims have reportedly been notified of the impending charges. The legal basis for bringing charges against a former head of state for actions taken in that capacity will likely be a key aspect of the case moving forward.

Further details regarding the evidence the Justice Department intends to present and the specific legal statutes under which Castro will be charged are anticipated in the afternoon press conference. This story remains a developing situation.
