The right to freedom of expression is currently facing a global crisis unleashed by the conflict in Gaza. The conflict has led to a high polarisation of public opinion, with opposing factions supporting either Israel's actions or the Palestinian cause. Yet, the right to freedom of expression of Palestinian activists and their supporters is facing systematic suppression worldwide. In this column, I shed light on how state and non-state actors have been active vehicles for the restriction of the right to freedom of expression by targeting voices in support of the Palestinian cause and I consider the application and scope of the right to freedom of expression in this context. The column concludes that the failure to protect the right of Palestinians to have their voices heard contributes to the erosion of our collective right to freedom of expression and has wider repercussion on the promotion and protection of human rights more generally.
