At least 538 people have been killed since demonstrations began two weeks ago, according to figures from the U.S.-based Human Rights Activists News Agency.

Demonstrations broke out in Iran on Dec. 28 and have spread nationwide as protesters vent their increasing discontent over the Islamic Republic’s faltering economy and the collapse of its currency.

Tehran warned the US and Israel against any intervention over nationwide protests in Iran, as demonstrations entered their third week and fatalities mounted.

Iran’s diplomatic moves, not calling for assistance or reaching out to its allies, seem to be intended to show that Tehran believes everything is going to turn out all right. Iran has faced almost two weeks of protests.

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.

Protests in Iran have continued despite threats from the government to crack down. Online videos show demonstrators protesting Friday night, even after authorities shut down the internet and cut phone lines.

President Trump said on Sunday that he is looking at "very strong options" when is comes to supporting the protest movement in Iran. Why it matters: Trump's remarks come as the protests in Iran intensify and the death toll rises. Trump said publicly that he was willing to use military force if the Iranian regime killed protesters.

More than 570 protests have taken place across all of Iran’s 31 provinces. The death toll has reached at least 116 with more than 2,600 arrests.
