About 100 women disrobed yesterday in a square in downtown Asuncion to protest nuclear weapons.
Demonstrator Carola Gonzalez said the Humanist Party activists decided to strip for their cause since "the public and the news media pay so much attention to breasts and bottoms."
Many went topless, with their chests colorfully painted with slogans, images of the Earth and radioactivity symbols.
Organisers said they hoped to raise awareness about the thousands of nuclear warheads threatening the planet, about half them in the hands of the US Some 20 police officers - and a crowd of onlookers - monitored the protest.
