U.S. President Donald J. Trump has warned Iran’s leadership that they are dangerously close to crossing a U.S. “red line” for acting against that country militarily.

The U.S. threat comes as Iranian government authorities have massacred more than 500 Iranian civilians during protests in Tehran and other Iranian cities in pro-democracy demonstrations.

Iran’s Supreme Leader has threatened the death penalty for protesters and has killed the internet in that country.

The protests are entering their third week of demonstrations and have resulted in the seizure of government buildings and has, for the first time, seriously threatened to topple Ayatollah Ali Khamenei and the Iranian theocracy that has ruled Iran since 1979.

Many called for the return of the Shah, who was deposed during the Islamic Revolution in that country in 1979.

The protests began with young Iranians who were angered by the recent economic collapse caused by U.S. economic sanctions.
