The Iranian government declared three days of national mourning on Sunday for the "martyrs" killed in the recent protests, according to the state broadcaster.

The move came amid rising fatalities from two weeks of nationwide unrest, which Iran has blamed on the United States and Israel, The Caspian Post reports, citing foreign media.

Semi-official Tasnim news agency reported that at least 111 members of Iran's security forces have been killed in clashes since the protests initially erupted over a sharp depreciation of the rial and sweeping subsidy reforms.

In response to the unrest, the government on Sunday called for nationwide protests in support of the Islamic Republic on Monday.

In a televised interview with the state broadcaster IRIB on Sunday, Iranian President Masoud Pezeshkian stated that his government is prepared to address the economic grievances driving the protests, but warned that "rioters" will not be tolerated.

Pezeshkian also detailed the government's plans to implement a major subsidy reform program aimed at stabilizing markets, boosting production, and increasing purchasing power, providing an update on its current progress.
