An NHS doctor who said Hamas terrorists were oppressed resistance fighters held up an "anti-Semitic" sign at a pro-Palestinian protest, a tribunal heard.
Dr Ellen Kriesels was photographed holding a placard of the Israeli flag surrounded by the words "rape, steal, cry, kill, cheat, lie".
Her posts on X included repeated accusations about Jewish "supremacy" and claims that Judaism was a "racist, imperialist and genocidal religion".
She claimed Hamas was a political party, called its members "oppressed resistance fighters, not terrorists", and claimed yellow ribbons worn in support of Israeli hostages were "a visual sign of Jewish supremacy".
Dr Kriesels, a consultant developmental paediatrician who works at Whittington Hospital in north London, appeared at a Medical Practitioners Tribunal Service hearing in Manchester on Friday.
The tribunal made an interim order of suspension for nine months. It said there were concerns regarding her fitness to practise, which posed a "real risk to members of the public and which may adversely affect the public interest".
The tribunal noted that members of the public might believe she holds "biased views" and be hesitant to be treated by her and, taking all information into account, it was satisfied she "could pose a real risk to public safety".
The General Medical Council (GMC) had sought an 18-month suspension due to concerns about patient safety and public confidence in her profession.
Opening the case for the GMC, Ms Isobel Thomas said it had received a complaint about the doctor from the UK Lawyers for Israel (UKLFI).
Ms Thomas said the hospital trust had received more than 1,500 emails, many from patients, alleging that Dr Kriesels's actions were "anti-Semitic and racist".
She said colleagues had also expressed concern about working with her, and the trust had launched a preliminary investigation and suspended her in September. A complaint was also made to police but no action was taken, the tribunal also heard.
The trust had asked her take down the posts but she had refused, Ms Thomas said, and when challenged about the placard, the doctor said "it doesn't matter what people say" and she was "only expressing facts".
The tribunal heard how the doctor had displayed the placard at several demonstrations, including one organised by the Palestine Coalition in central London in September.
One of the doctor's social media posts claimed: "Most Jews, Zionist or not, centre their Jewish identity in the midst of this genocide which is 'proof' of supremacy."
Talking about the Hamas terror attack on Israel on Oct 7 2023 she said: "Some Jews 'merely' say it was a progrom [sic]. Other Jews 'merely' say that it was antisemitic. Always trying to frame the Jews as victims. So ridiculous. So excruciating. So exhausting."
And in response to a comment by the actress Miriam Margolyes about Gaza that "Hitler won; he changed us", Dr Kriesels said: "Why mention your sense of victimhood AT ALL when your fellow Jews are committing a gleeful genocide."
Ms Thomas said: "Her anti-Semitic views may impact on her ability to provide safe care to members of the population. Jewish families may be concerned they will not receive impartial care from her."
An 18-month interim order of suspension was necessary to protect the public, she said, adding that the doctor had no protection under Article 10 of the European Convention on Human Rights relating to freedom of expression to make anti-Semitic or racist statements.
Dr Kriesels claimed her actions were not anti-Semitic or racist but "anti-Zionist", and that she had acted in a personal capacity, not as a NHS doctor. She was the victim of "orchestrated harassment", the tribunal heard, and the allegations against her led to concerns about her personal safety.
Giving evidence, Dr Kriesels said she had been deeply affected by the "genocide" in Gaza and "horrified" by what Israel was doing. She claimed: "I believe Zionism results in terrorism for Palestinians and Zionism should be demolished."
She added that the GMC should protect doctors from "vexatious accusations" and "shouldn't be policing matters of free speech".
Richard O'Dair, the doctor's counsel, argued that she had never been the subject of any complaints in her 14 years of clinical practice, and a suspension for "expressing opinions about genocide in Gaza" would have a "chilling effect" on free speech and colleagues.
A GMC spokesman said: "The Interim Orders Tribunal has agreed with our submission and suspended Dr Kriesels' registration while we continue our investigation into her fitness to practise. Our focus is to complete our investigation swiftly, fairly and proportionately."
