Mia Farrow has ended her hunger strike  after 12 days.

Farrow, 64, had been subsisting on a liquid diet since April 27 to raise more awareness for the Darfur humanitarian crisis.

"I have been instructed by my doctor to stop my fast immediately due to health concerns — including possible seizures," she tells Entertainment Tonight. "I am fortunate. The women, children, and men I am fasting for do not have this option."

"When I began this fast twelve days ago," Farrow continues, "I hoped another would take my place, and another, and another, until the expelled humanitarian agencies are readmitted and finally there can be justice and peace for the people of Darfur. Richard Branson has stepped forward and so I have ended this fast."

Branson — the 58-year-old British founder of Virgin Atlantic Airwaysand the Virgin record label and music store chain — said he is "honored" to be taking over the fast for the next three days.
