Iran has warned that it will strike Israel and US military bases, in the event of strikes on Iranian territory following weeks of escalating protests in the country.
At least 192 people have been killed in the largest protest against the Iranian government for over three years, according to Iran Human Rights.
The Norway-based NGO warned that the deaths "may be even more extensive than we currently imagine".
Iran has been under an internet blackout for over 60 hours, according to monitor Netblocks, making it difficult to verify information, including the death toll.
US President Donald Trump has threatened to intervene in recent days, warning Iranian leaders against using force on protesters. He warned on Saturday that the US stood "ready to help".
