HAVANA, CUBA - Before Pope Francis makes his way to the states next week, he's making a three-day stop in Cuba. 

The pontiff will arrive in Havana Saturday, hoping to spread a message of peace and unity in the wake of the island nation's renewed ties with the United States.

The pontiff is already getting a jump start on sharing a message with Cubans and Americans.  He spoke remotely with a young group of students in Havana and New York, promising to push for better diplomatic relations between their two countries.

A bullet was buried at the base of an olive branch at the end of the conversation -- a symbol of the pontiff's hope for peace.

The pope's message to all Cubans was broadcast Thursday night on state television.  It was the first time a sitting pope previewed his visit on TV before his arrival.
