Campaigners join hands around almost 8,000 photographs of Iran's seven imprisoned Baha'i leaders at a rally calling for human rights in Iran, held at Rio's Copacabana Beach, 19 June 2011. Their yellow vests read, "Today we are all Baha'is" and "Free the 7 Baha'is imprisoned in Iran". Vests were also distributed to beach-side traders and passers-by who wished to identify themselves with the cause.
