Stuttgart – Climate activist Greta Thunberg made a surprise appearance at the trial of five individuals accused of attacking an Israeli defense company in Ulm, Germany. The 23-year-old Swede, who rose to prominence as a climate advocate but has increasingly focused on the Israeli-Palestinian conflict, attended the fourth day of proceedings on May 22, 2026. During the hearing, she formed a heart gesture with her hands directed at the defendants, signaling solidarity with the group known as the 'Ulm 5'.
The Case: What Are the 'Ulm 5' Accused Of?
The five defendants – three women and two men aged between 23 and 39 – are from the United Kingdom, Ireland, Spain, and Germany. According to the indictment, they broke into the Ulm facility of Elbit Systems, an Israeli defense company, on the night of September 8, 2025. Once inside, they deliberately destroyed computing equipment, telephones, and laboratory technology valued at approximately €1.04 million. The attack is described as politically motivated, targeting a company that supplies military technology to Israel.
The group was arrested at the scene. A photograph taken before the incident shows the five individuals posing with a Palestinian flag, which was later circulated on social media under the hashtag 'Ulm 5'. The state prosecutor’s office has charged them with membership in a criminal organization, damage to property, and the use of symbols of terrorist organizations. The indictment alleges that the group is part of 'Palestine Action Germany', an network that denies Israel’s right to exist and uses Hamas-associated imagery.
Greta Thunberg’s Shift in Activism
Thunberg’s presence at the trial underscores her evolving public image. Once celebrated as a global icon for climate action, she has increasingly turned her attention to the Israeli-Palestinian conflict since the October 7, 2023 Hamas attack on Israel and the subsequent war in Gaza. In 2024, she participated in a demonstration in Berlin marking the anniversary of the attack, which drew criticism for its militant tone and alleged antisemitic undertones.
Thunberg has been accused of aligning with extremists who voice anti-Israel sentiments. In Stuttgart, her heart gesture was interpreted as a direct show of support for the accused. The gesture came on a day when the trial had already seen disruptions: the first hearing was halted after defense lawyers caused a disturbance, and on the second day, spectators shouted slogans as the defendants were led into the courtroom in handcuffs. On a previous occasion, one of the accused had to be carried into the room due to non-compliance.
Trial Tensions and Legal Proceedings
The trial has been marked by high emotions. On the fourth day, defendants entered the room under applause from supporters. Presiding judge Anja Müller has repeatedly warned the audience about maintaining order. The charges include not only property damage but also the use of symbols linked to organizations designated as terrorist by the European Union, including in some cases the Hamas movement. The state prosecutor emphasized that the actions were not mere vandalism but part of a coordinated campaign to intimidate and disrupt Israeli businesses in Germany.
Defense lawyers argue that their clients are peaceful activists exercising their right to protest against Israeli military actions in Gaza. They claim the damage to Elbit Systems was a legitimate act of resistance against what they call war profiteering. The court is expected to hear evidence from police investigators and forensic experts over the coming weeks.
Broader Context: Pro-Palestine Activism in Germany
The case reflects wider tensions in Germany regarding pro-Palestine activism. Since October 7, 2023, German authorities have cracked down on demonstrations that cross into antisemitism, including the use of slogans such as 'From the river to the sea' in certain contexts. The 'Ulm 5' case is one of several high-profile trials involving activists who targeted Israeli-linked companies.
Human rights groups have raised concerns about the criminalization of political speech, while Jewish organizations accuse the activists of fomenting antisemitic violence. The trial has drawn international media attention, with Thunberg’s involvement amplifying the spotlight. Some observers note that Thunberg’s reputation for moral clarity has suffered as she wades into a complex conflict, but her supporters argue that she is consistent in opposing oppression and corporate harm.
Greta Thunberg first gained fame in 2018 at age 15, when she began skipping school to protest outside the Swedish parliament, demanding stronger action on climate change. She inspired a global movement of school strikes and addressed world leaders at the United Nations. However, in recent years, she has shifted her focus to what she describes as 'intersectional' activism, linking climate justice to social issues such as Palestinian rights. Critics say she is being manipulated by radical groups, while allies praise her willingness to take unpopular stances.
The Stuttgart trial continues, with verdicts expected in the summer of 2026. Regardless of the outcome, the case has become a flashpoint in debates over the limits of political protest and the role of international figures in domestic legal battles. Thunberg’s gesture may be seen as a minor moment, but it signals the deep divisions that the Israeli-Palestinian conflict continues to generate far beyond the Middle East.
