The United Nations Children's Emergency Fund welcomed Bollywood superstar Amitabh Bachchan as its International Goodwill Ambassador.
Amitabh signed a formal letter with UNICEF Executive Director Carol Bellamy on Thursday evening.
Amitabh's association with UNICEF began in 2002, with his appearance in a series of award-winning television and radio commercials encouraging parents to vaccinate their children against polio.
