Iran says US trying to violate sovereignty over unrest, warns of response

US attempts to violate Iran's sovereignty over the issue of protests triggered by the death of a woman in police custody will not go unanswered, the foreign ministry said on Monday.

Iran has been rocked by nationwide demonstrations sparked by the death of 22-year-old Kurdish woman Mahsa Amini, after she was detained by morality police enforcing the Islamic Republic's strict restrictions on women's dress.

The case has drawn international condemnation. Iran has said the US was supporting rioters and seeking to destabilise the Islamic Republic.

"Washington is always trying to weaken Iran’s stability and security although it has been unsuccessful," Iran's Foreign Ministry spokesperson Nasser Kanaani told Nour news, which is affiliated with a top security body, in a statement.
