DUBAI, United Arab Emirates -- Iran said it executed two men Saturday convicted of allegedly killing a paramilitary volunteer during a demonstration, the latest executions aimed at halting the nationwide protests now challenging the country's theocracy.The Basij have deployed in major cities, attacking and detaining protesters, who in many cases have fought back.Amnesty International has said the trials “bore no resemblance to a meaningful judicial proceeding.”State TV also aired footage of Karami and Hosseini talking about the attack, though the broadcaster for years has aired what activists describe as coerced confessions.The men were convicted of the killing, as well as “corruption on Earth,” a Quranic term and charge that has been levied against others in the decades since the 1979 Islamic Revolution and carries the death penalty.Women have played a leading role in the protests, with many publicly stripping off the compulsory Islamic headscarf, known as the hijab."
