French police said the German authorities, who had previously refused Abu-Sitta entry to Germany in April, had put a visa ban on him for a year, meaning he was banned from entering any Schengen country.

During the months of October and November 2023 at the beginning of Israel’s war on Gaza that has since killed more than 34,000 Palestinians, Abu-Sitta operated from Gaza’s al-Shifa and al-Ahli Baptist hospitals. During his 43 days, he described witnessing a “massacre unfold” in Gaza and the use of white phosphorus munitions, which Israel has denied. He has also provided evidence to Scotland Yard.

“How can Germany issue territorial bans throughout the Schengen area? It’s mind-boggling! This is a new step in the repression of everything to do with Palestine,” said Poncet Monge, who later posted a photograph of Abu-Sitta attending the conference via video.

“We are outraged that he cannot be present among us,” she said.
