Iran is experiencing its largest anti-government protests in years, initially sparked by economic grievances but now targeting the ruling system. Reports indicate a significant death toll, with activists claiming hundreds killed and thousands arrested, though official figures are not provided. Authorities have imposed an internet blackout, raising fears of a harsher crackdown. In response to potential US intervention, Iran has warned that Israel and US military bases would be legitimate targets. Israel, meanwhile, is on high alert, with its Prime Minister discussing the situation with the US Secretary of State.
