Thousands of government supporters staged rallies in Iran for a fourth day on Saturday in a backlash against widespread anti-government protests that the clerical establishment has blamed on the country's enemies.

Saturday's show of support took place a day after Iran's foreign minister said a United Nations Security Council meeting called by the United States to discuss the protests had proved a "blunder" by the administration of U.S. President Donald Trump.

State television showed rallies and marches in more than a dozen cities with demonstrators waving Iranian flags and chanting slogans including "Death to America," "Death to Israel" and "Death to Britain."
