Hillary Clinton has beaten Democratic rival Barack Obama in a critical vote in the US state of Pennsylvania.
Speaking to cheering supporters, she said the American people deserved "a president who doesn't quit". She added: "Because of you, the tide is turning."
Mrs Clinton still trails Mr Obama in terms of delegates but this victory keeps her campaign alive, analysts say.
Mr Obama had predicted he would lose but said he had made big progress in reducing Mrs Clinton's initial lead.
With 75% of returns counted, Mrs Clinton was leading Mr Obama by 54% to 46%.
