A prominent Egyptian rights lawyer has been banned from travel after airport authorities canceled his trip to France.

Airport officials say authorities on Wednesday notified Malek Adly — who was released from solitary confinement in August after being held for more than 100 days — that he is banned from travel by a judicial order. They spoke on condition of anonymity because they were not authorized to speak to the media.

Adly was incarcerated on a rolling series of administrative detention orders, facing several accusations including attempting to overthrow the government.

His supporters say he was targeted for publicly challenging President Abdel-Fattah el-Sissi's April decision to transfer sovereignty of two Red Sea islands to Saudi Arabia.

On his Facebook page, Adly commented: "I don't know how to thank you, Egypt."
