Over 500 people have been killed in two weeks of unrest in Iran, a rights group said on Sunday, as Tehran threatened to attack American military bases in the Middle East if the U.S. hits first.

Demonstrations that began as outrage at the state of the economy have spread to cities across the country, amid an escalating crackdown by the authorities.

Protesters in Iran defied a deadly government crackdown on Saturday night, taking to the streets despite reports suggesting hundreds of people have been killed or wounded by security forces in the past three days.

At least 116 people have been killed in the anti-government across Iran, according to data published on Saturday by the Human Rights Activists News Agency.

Retired Gen. Jack Keane says the Trump administration should issue a final warning to Iran before acting against leaders he blames for violent crackdowns on protesters.

As furious protests enter their third week and bring Iran to the precipice of change, the country’s theocratic government is trying to survive by harshly cracking down on the widening demonstrations.
