The former Cuban leader Fidel Castro has warned of the dangers of nuclear war, in his first speech to the Cuban national assembly for four 4 years. Mr. Castro, who ceded power to his brother Raul after he had a stomach surgery in 2006, claimed that the United States was planning to attack Iran and North Korea. Michael Voss reports from Havana.

It was an assured solid performance. Mr. Castro’s voice was stronger than at any time since he'd re-emerged into the public eye about a month ago. There was no mention in the speech of Cuban politics or the changes that his brother is pushing through. It appears he’s found a new mission in later life - to save the world from nuclear destruction.

The Columbian president-elect Juan Manuel Santos has been sworn in at a ceremony in the capital Bogotá. More than 100 international delegations attended the inauguration, including the left wing President of Ecuador and the Foreign Minister of Venezuela. Both countries broke off relations with Mr. Santos’ predecessor Alvaro Uribe.
