About 20,000 people took part in Switzerland's biggest anti-nuclear march in 25 years on May 22, Swissinfo.ch said that day.
“Chanting and waving placards, anti-nuclear protesters marched in two groups to the site of Beznau, Switzerland’s oldest nuclear power plant which is located in canton Aargau,” the article said.
Organisers said about 150 political parties and environmental organisations joined the march.
Swissinfo.ch said about 40% of Switzerland's energy comes from nuclear power. A protest organiser said: “The catastrophe at Fukushima has entirely changed the debate about energy. Politicians and power companies can no longer ignore it.”
On May 25, the Swiss government announced it planned to phase out nuclear power by 2034, Bloomberg said that day.
