Clinton treated for concussion

US Secretary of State Hillary Clinton sustained a concussion last week after becoming extremely dehydrated and fainting while suffering from a stomach virus, the State Department said.

The 65-year-old Mrs Clinton is recovering at home and has been advised by her doctors to continue to rest and avoid strenuous activity and cancel all work events for the next week. She had been scheduled to testify before a pair of congressional panels looking into the September 11 attack against a diplomatic outpost in Benghazi, Libya.
