LONDON — Protesters across the world called on Iran on Saturday to end its clampdown on opposition activists, demanding the release of hundreds rounded up during demonstrations against the country’s disputed election.
Groups including Human Rights Watch and Amnesty International backed a global day of action, with protests planned in more than 80 cities.
The protesters want Iranian authorities to release what they say are hundreds, or even thousands, of people detained during protests that followed the presidential election last month that returned Mahmoud Ahmadinejad to power.
Inside Iran, as well, Iranian police and pro-government militia attacked and scattered hundreds of protesters who had gathered in Tehran in response to the global demonstrations of solidarity, witnesses said.
Police said about 600 protesters joined a “noisy but peaceful” demonstration outside the Iranian embassy in London. It was one of a series of events in cities across Europe, including in Brussels, Belgium; Amsterdam; Vienna; and in front of U.N.’s European headquarters in Geneva.
In Brussels, protesters held placards carrying images of the detained or dead, including Neda Agha Soltan, the 27-year-old whose death — beamed around the world on the Internet — became a rallying cry for opponents of the regime.
Several hundred protesters gathered behind police barricades just off Times Square in New York City. One man hoisted a green placard, splattered with red, that read, “Where is my vote?” The crowd chanted, “Stop the killing. Stop the torture.”
A small group of Iranians in New York have been on a three-day hunger strike and are holding frequent demonstrations outside the United Nations to call on the world body to investigate human rights abuses in Iran. About 350 people gathered in downtown Vienna, and about 150 protesters gathered in Rome. In Norway, about 250 Iranian emigres met at a conference center on the outskirts of Oslo, and about 3,000 people gathered in Stockholm and others in Copenhagen.
