A surgeon who flew to Cuba to treat the ailing Cuban leader, Fidel Castro, is to examine whether he should undergo further surgery.
Dr Jose Luis Garcia Sabrido, chief surgeon at Madrid's Gregorio Maranon hospital, travelled to Havana last Thursday.
He said that Madrid's health department has been sending medicines to Cuba since June, but he declined to say which medical material or anything about Castro's condition.
He said Spain would continue to give its support and assistance to the Cuban government.
Castro, 80, has not appeared in public since undergoing emergency intestinal surgery in July.
Castro has placed his younger brother, Raul, in charge of the government.
