The first of three ships carrying food, medical supplies, solar panels, and other humanitarian aid arrived in Cuba on Tuesday, three days behind schedule, as the island grapples with a worsening economic and energy crisis.

The vessel, named Granma 2.0 after the yacht that carried Fidel Castro from Mexico to Cuba in 1956, was accompanied by activist Thiago Avila and escorted by the Mexican Navy until it reached Cuban waters.
