The leader of the Cuban Revolution, Fidel Castro, met on Tuesday with some of the 1,000 passengers aboard the Peace Boat, which was docked in Havana for a visit. 

The meeting at Havana's Conference Center was attended by 620 activists, crew members and other passengers of different ages, countries and professions who are on a three-month, worldwide voyage to promote peace throughout the world. 

Junko Watanabe, a survivor of the U.S. atomic attack on the Japanese city of Nagasaki who is living in Brazil, also took part in the meeting. 

Peace Boat is an international non-governmental and non-profit organization that works to promote peace, human rights, equal and sustainable development and respect for the environment.
