Egypt's official news agency says Omar Suleiman, the long-time head of intelligence under ousted leader Hosni Mubarak, has died in the United States where he went for medical treatment.
The official Middle East News Agency said Suleiman "died in the early hours of Thursday [July 19] in a hospital in the United States," but gave no details about the cause of death.
Suleiman, 76, briefly served as vice president during the uprising that toppled Mubarak in February 2011, after some 30 years as Egypt's ruler.
Suleiman's aide, Hussein Kamal, was quoted by Reuters as saying Suleiman's death happened "suddenly while he was having medical tests" in the city of Cleveland.
The aide offered no cause for the death.
Suleiman became a conspicuous face as the regime responded to Arab Spring events culminating in Mubarak's ouster in early 2011.
Suleiman was disqualified
from the 2012 presidential election on the grounds that he had failed to secure the required number of endorsements from all of the country's provinces.
Suleiman was seen by human rights groups as being responsible for the mistreatment and torture of detainees, including opposition activists.
