Fatemeh Mohajerani, the spokesperson of the Iranian government, said the ongoing internet restrictions were implemented to protect citizens and counter cyberattacks amid what she described as psychological warfare and digital threats by Israel.
She said ministers are working around the clock with the president and key cabinet members inspecting infrastructure and public services on the ground.
Authorities warned that national internet services could replace global access if necessary and urged citizens to rely solely on state media and domestic messaging apps for news.
Mohajerani added that any perceived insult to the Supreme Leader would trigger a "widespread reaction" from the public.
