Iranians joined protests on the streets of Tehran and other cities for the second day in a row Sunday, following the Iranian government’s admission that it shot down a Ukrainian Airlines passenger jet Wednesday, killing all 176 people on board. The government had previously insisted that allegations of a missile strike were Western propaganda. As Henry Ridgwell reports, Iran’s government is facing growing pressure both from abroad and at home -- but it’s not clear if the protests will develop into bigger anti-government demonstrations.
