Libyan intelligence chief Abdul Qader al-Tuhami died of a heart attack at his home in the capital Tripoli on Sunday, according to a local security source.
The Libyan government has yet to confirm al-Tuhami's death.
Al-Tuhami had served as an officer in the external security service under late ruler Muammar Gaddafi.
In April 2017, he was appointed by Libya's Presidential Council as head of the intelligence service.
