Greta Thunberg was arrested in London for supporting the organization Palestine Action, during a demonstration.

Environmental activist Greta Thunberg was arrested in London after displaying a banner in support of the organization Palestine Action, which is banned in the UK. The police stated that the arrest was made under Article 13 of the Terrorism Act 2000. Thunberg participated in a demonstration outside the Aspen Insurance headquarters, criticizing the company for its ties to the Israeli defense industry. The protest was organized to support activists from Palestine Action who are on hunger strike, demanding an end to the UK's collaboration with arms factories supplying weapons to Israel.

The British government, led by Prime Minister Keir Starmer, has refused to intervene in the legal proceedings, citing the independence of the judiciary. Thunberg's arrest has been criticized by organizations that support human rights, which believe that support for political prisoners should not be considered terrorism. Since the banning of Palestine Action, approximately 2,500 people have been arrested in the UK for expressing support for this organization.
