Trump says US will intervene if Iran starts killing protesters: ‘Locked and loaded’

President Trump warned the US would intervene if Iran begins killing protesters, as demonstrations fueled by economic collapse spread beyond Tehran and raise fears of a violent crackdown.

Some of the most severe violence has been reported in western Iran, where videos circulating online appeared to show fires burning in streets and the sound of gunfire during nighttime protests.

The demonstrations come amid heightened regional tensions following a 12-day conflict with Israel in June, during which the United States bombed Iranian nuclear sites. Iranian officials have since said the country is no longer enriching uranium, attempting to signal openness to renewed negotiations over its nuclear program to ease sanctions.
