Tens of thousands of Iranians took part in the funeral of a senior dissident cleric in Isfahan on Tuesday, which turned into the biggest anti-government protest for years, the BBC reported.
The protesters chanted slogans against the government and the supreme leader, Ayatollah Ali Khamenei, calling for the "death to the dictator." Among other slogans, they chanted "The political prisoners must freed" and "Mousavi and Karroubi must be freed," referring to the leaders of the reformist green movement who are under house arrest in Tehran.
Ayatollah Jalaluddin Taheri, who died at the age of 87, was a major opponent of the hardliners in Iran's government and resigned in protest.
Iran's presidential elections are due to take place in 10 days.
