President John F Kennedy's sister Eunice Kennedy Shriver, founder of the Special Olympics, has died aged 88.
Tributes have been flooding in, including one from President Barack Obama. He said he was saddened by her death, calling her a "champion" for disabled people.
She organised the first Special Olympic Games in 1968, partly inspired by her mentally disabled sister, Rosemary Kennedy.
Eunice, mother of California First Lady Maria Shriver Schwarzenegger, passed away on Tuesday morning at a Cape Cod hospital, where she has been in a critical condition for a week.
No information was given about the cause of her death.
