A lot of people are worried,” they said. “There is a lot of death, sadness and anger.”A commander in Iran’s elite Islamic Revolutionary Guard Corps (IRGC) also said the country’s armed forces remained on high alert.IRGC Ground Force Commander Brigadier General Mohammad Karami said the military was “ready at the highest possible level”, Iran’s state-run Press TV reported.Separately, Iranian Defence Minister Aziz Nasirzadeh warned that the government would use all its capabilities to “suppress the savage armed terrorists” it claims are behind the unrest.In comments broadcast on Iranian state television, Nasirzadeh reiterated previous claims by the government that the demonstrations were orchestrated by the US and Israel.The “designers and executors of the riots should know that we are monitoring them”, he added.Meanwhile, despite Trump’s softening tone, Washington issued fresh sanctions against Iran on Thursday morning over the protest crackdown.The measures targeted Ali Larijani, the secretary of Iran’s Supreme National Security Council (SNSC), and several other officials, whom Washington accused of being the “architects” of the Iranian government’s “brutal” response to the demonstrations.
