Hannibal Gaddafi, the late Libyan leader Muammar Gaddafi's son, has been transferred from a Lebanese prison to a hospital in "critical condition," according to Dubai-based Al-Hadath TV.

Last month, Gaddafi embarked on a hunger strike to protest his confinement without trial since 2015. According to unnamed sources, Al-Hadath had a severe dip in his blood sugar level.

Gaddafi has been prosecuted in Lebanon for withholding information about the whereabouts of Imam Musa al-Sadr, a Lebanese Shi'ite Muslim imam who went missing in Libya in 1978. Hannibal was three years old at the time of the Imam's disappearance.

According to one of his lawyers, Hannibal, 47, has "spasms in his muscles, hands, and legs, dizziness and headaches, and prior medical problems in his spine and hips deteriorated because of the hunger strike.

Hannibal escaped to neighbouring Algeria with his wife and some of his siblings in 2011, following Tripoli's collapse and his father's death at the hands of opposition militants. They then sought asylum in Syria as political refugees under the administration of Bashar al-Assad.

According to his lawyers, Hannibal was "lured" to the Syrian-Lebanese border in 2015 under the guise of a newspaper interview. He was briefly kidnapped and transferred to Lebanon by a gang seeking information concerning al-Sadr.

Members of Hannibal's most recent legal team, which took over barely one month ago, told Al Jazeera that they are prepared to take his case to the international stage with the assistance of "humanitarian associations."

Hannibal has insisted on his innocence. In a letter from Saudi TV Al Hadath in 2022, Gaddafi questioned how a youngster could know where the Imam was.

Adding that He is an innocent man, and his only crime is that he is Gaddafi's son. Apart from that, he hasn't done anything.
