Protests in Iran are intensifying due to the country's struggling economy, putting pressure on its theocracy as it has shut down the internet and telephone networks.

Anti-government protests in Iran appeared to accelerate, sparked by economic woes and disillusionment with Tehran's clerical leaders.

"Regime teeters in Tehran" reads the headline of the Times, leading on remarks from US President Donald Trump, after he told Fox News that Iran's Supreme Leader Ayatollah Ali Khamenei was "looking to flee the country".

Tens of thousands of Iranians poured into the streets on Friday night in a second night of mass, nationwide antigovernment protests despite a total internet blackout and threats of a severe crackdown from the senior Iranian leadership.

Iran’s unrest has now stretched into 12th straight day, triggered by economic anger and a collapsing currency. Iran Supreme Leader Khamenei has warned of a crackdown, alleging US role in fueling the protest.

Iran remains offline as protests spread nationwide, leaving at least 62 dead, thousands detained, and tensions rising between Tehran and Washington.

Iran's judiciary chief has vowed decisive punishment for protesters, signaling a coming crackdown against demonstrations.
