Hannibal Qaddafi, son of the late Libyan leader Muammar Qaddafi, has been moved from a Lebanese prison to hospital in "critical condition", Reuters reported on Sunday, citing Dubai-based Al-Hadath TV.
Qaddafi went on hunger strike last month in protest at his incarceration without trial since 2015.
Al-Hadath, which cited unidentified sources, said he had suffered a sharp drop in his blood sugar level.
Qaddafi has been charged in Lebanon with concealing information about the fate of Imam Musa al-Sadr, a Lebanese Shiite Muslim cleric who disappeared while on a trip to Libya in 1978.
His father, Muammar Qaddafi was captured and killed by rebels in 2011.
The dictator had eight children, most of whom played significant roles in his regime. His son Muatassim was killed at the same time Qaddafi was captured and slain. Two other sons, Seif al-Arab and Khamis, were killed earlier in the uprising.
Another son, Seif al-Islam, was released by a militia in the town of Zintan in 2017, after he had been held there for six years. Another son, Hannibal, is reportedly detained in Lebanon.
In 2021, another of Qaddafi’s sons, al-Saadi Qaddafi, was released by Libyan authorities after more than seven years of detention in the capital of Tripoli.
