The pro-government demonstration, which began shortly after sunrise on Havana’s waterfront, comes as Cuban officials rallied this week around the island’s revolutionary hero amid spiraling tensions with the US.

The 94-year-old elder statesman was not present.

Cuban lawmaker Gerardo Hernández, a national hero and former spy, conveyed a message thanking the Cuban people and friends around the world for their solidarity.

“As long as I live, I will remain at the forefront of the Revolution, with one foot in the stirrup,” Hernandez quoted Castro as saying.

Thousands of Cubans waved flags during the nearly hour-long rally beside a calm sea just 90 miles from US shores, chanting “Viva Raul!” and “Patria o Muerte (Homeland or Death)!”.

President Miguel Diaz-Canel and Prime Minister Manuel Marrero attended the rally, as did several of Castro’s family, including daughter Mariela Castro, son Alejandro Castro and grandson Raúl Rodríguez Castro.

Rodriguez Castro, known in Cuba as “Raulito (Little Raul)” or “El Cangrejo (The Crab)”, often serves as his grandfather’s bodyguard and met last week with CIA director John Ratcliffe during a rare visit by a US spy chief to Havana.

Cuba says Castro’s indictment on murder charges on Wednesday was based on “spurious” allegations designed to serve as a pretext to invade as President Donald Trump’s administration pushes to upend the island’s government.
