<p data-start="64" data-end="318"><span style="font-family: georgia, palatino, serif; font-size: 12pt;">Swedish climate activist Greta Thunberg was arrested in London on Tuesday during a pro-Palestinian protest, according to a UK-based campaign group. The arrest took place amid demonstrations targeting companies allegedly linked to Israel&rsquo;s defence sector.</span></p>
<p data-start="320" data-end="702"><span style="font-family: georgia, palatino, serif; font-size: 12pt;">Green Party leader and London Assembly member Zack Polanski said Thunberg was detained for &ldquo;holding a sign opposing genocide,&rdquo; criticising the action as a threat to democratic values. In a post on social media platform X, Polanski said the arrest reflected poorly on the United Kingdom&rsquo;s current political climate and accused the Labour government of criminalising peaceful protest.</span></p>
<p data-start="704" data-end="972"><span style="font-family: georgia, palatino, serif; font-size: 12pt;">Polanski also shared a video showing Thunberg sitting cross-legged on the ground, holding a placard that read, &ldquo;I support Palestine Action prisoners. I oppose genocide.&rdquo; The footage shows a police officer removing the sign before she was reportedly taken into custody.</span></p>
<p data-start="974" data-end="1221"><span style="font-family: georgia, palatino, serif; font-size: 12pt;">The campaign group said the protest targeted Aspen Insurance in central London, claiming the firm provides services to Elbit Systems, an Israeli-linked defence company. The demonstration escalated when red paint was allegedly thrown on a building.</span></p>
<p data-start="1223" data-end="1497"><span style="font-family: georgia, palatino, serif; font-size: 12pt;">Police later confirmed that two people were arrested in connection with the incident. Authorities said Thunberg was detained for displaying a placard in support of a proscribed organisation, stating that the sign was linked to Palestine Action, which is banned under UK law.</span></p>
<p data-start="1499" data-end="1685" data-is-last-node="" data-is-only-node=""><span style="font-family: georgia, palatino, serif; font-size: 12pt;">The arrest has sparked renewed debate in the UK over the limits of protest, freedom of expression and the government&rsquo;s handling of demonstrations linked to the Israel&ndash;Palestine conflict.</span></p>
