Hillary Clinton in hospital with blood clot after fall

US Secretary of State Hillary Clinton, 65, has been admitted to hospital in New York with a blood clot, officials say.

Mrs Clinton suffered a concussion earlier this month after fainting and falling down. She was reported to have had a stomach virus at the time and to have passed out after becoming dehydrated.

Doctors discovered the clot during a follow-up examination on Sunday, her spokesman Philippe Reines said. "She is being treated with anti-coagulants and is at New York-Presbyterian Hospital so that they can monitor the medication over the next 48 hours," he said.

"They will determine if any further action is required."

It is not clear where the blood clot had formed.

Earlier this month, President Obama nominated Senator John Kerry - the Massachusetts Democrat who heads the Senate Foreign Relations Committee - to replace Mrs Clinton as secretary of state when she officially stands down at the end of January.

Mrs Clinton suffered from a blood clot previously. In 1998, while she was first lady, she had “the most significant health scare I’ve ever had,” she told the New York Daily News in an October 2007 interview. She recalled suffering what the newspaper described as “terrible pain” behind her right knee as she campaigned on behalf of New York’s Democratic Senator Charles Schumer.
