The US secretary of State Hillary Clinton has been admitted to a New York hospital with a blood clot that came from a concussion she suffered earlier this month.
The 65 year old suffered the concussion on 9 December after fainting and falling down with a stomach virus, and she has been off work and out of the public eye since then, although staff have said she has been working from home.
US officials have said that Mrs Clinton will return to work later this week. Her term as Secretary of State is due to end within the next few weeks, with Senator John Kerry due to come in as her replacement.
Clinton's illness meant she had to miss her testimony before the congressional committee earlier this month, who are investigating the attack on the US embassy in Benghazi, Libya, in which four US officials were killed including ambassador Christopher Stevens. Mrs Clinton has publicly accepted responsibility for the security failures which preceded the attack, and vowed to testify before her term is over.
