Iran has executed a second prisoner convicted over crimes committed during the nationwide protests challenging the country's theocracy, publicly hanging him from a construction crane as a gruesome warning to others.
The execution of Majidreza Rahnavard on Monday came less than a month after he allegedly fatally stabbed two members of a paramilitary force after purportedly becoming angry about security forces' killing of protesters.

Activists warn that at least a dozen people already have been sentenced to death in closed-door hearings. At least 488 people have been killed since the demonstrations began in mid-September, according to Human Rights Activists in Iran, a group that's been monitoring the protests. Another 18,200 people have been detained by authorities.

Iran’s Mizan news agency, which falls under the country’s judiciary, published a collage of images of Rahnavard hanging from the crane, his hands and feet bound, a black bag over his head.
Masked security force members stood guard in front of concrete and metal barriers that held back a gathered crowd early Monday morning in the Iranian city of Mashhad. Mizan alleged Rahnavard had stabbed two security force members to death Nov. 17 in Mashhad and wounded four others.
