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.Heavily edited footage aired on state television showed Karami speaking before a Revolutionary Court about the attack, which also showed a reenactment of the attack, according to prosecutors' claims.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."
