Pope Benedict XVI conducts open air mass in Cuba

Pope Benedict XVI urged Cubans to search for "authentic freedom" in his sermon at a huge open-air Mass in Havana's Revolution Square.

Hundreds of thousands of Cubans gathered to hear his words on the final day of his visit.

Pope Benedict is also due to meet the revolutionary leader and former President, Fidel Castro.
