US Secretary of State Hillary Clinton is resuming her official duties, five days after being released from a hospital for treatment of a blood clot.

Mrs Clinton, 65, will sit down with assistant secretaries of state for a closed-door meeting at the start of a week-long schedule containing nearly a dozen meetings, including three at the White House.

She was released from New York Presbyterian Hospital last Wednesday, after a stay of several days during which she was given blood thinners to treat the clot in a vein behind her right ear.

She has been resting at home in New York since then.

Mrs Clinton has suffered a series of ailments over the past month, including a stomach virus and a concussion.

Her doctors have said they expect her to make a full recovery.

The State Department said Mrs Clinton has been keeping up with her work by talking to her staff and receiving memos.

Her first White House meeting this week will take place tomorrow and include Secretary of Defense Leon Panetta and national security adviser Tom Donilon, the State Department said.

She is also scheduled to meet the Irish and South African ambassadors tomorrow and Afghan President Hamid Karzai later in the week.

Mrs Clinton will step down in the next few weeks.

US President Barack Obama has chosen Senator John Kerry, chairman of the Senate Foreign Relations Committee, to succeed her.
