Thousands of people have gathered in Tokyo to protest against a potential war on Iran, with some rallies reportedly taking place outside Japan's parliament. The demonstrations appear to be part of a larger global movement, with rallies also occurring in other cities around the world, although the exact nature and goals of these protests are unclear. The number of participants worldwide is reported to be in the thousands, with one outlet suggesting a much larger figure, but the specifics of the protests and their objectives vary across reports.
