Professor Ghassan Abu-Sittah, the British-Palestinian rector of the University of Glasgow and a reconstructive surgeon, has said he has been denied entry to France, where he was due to make a speech at the Senate.

“I am at Charles De Gaulle airport. They are preventing me from entering France. I am supposed to speak at the French Senate today. They say the Germans put a 1-year ban on my entry to Europe,” Abu-Sittah wrote on X, formerly Twitter.

“Fortress Europe silencing the witnesses to the genocide while Israel kills them in prison,” he added.

In April, Abu-Sittah was prohibited from entering Germany, where he was due to talk about his experiences in Gazan hospitals.

The surgeon spent 43 days in Gaza to help treat injured people last year, and in October said that counter-terror police “harassed” his family at his home in London.
