Hundreds of firefighters have held a demonstration in Tehran to protest their low salaries and poor living conditions amid high inflation and rising prices.

Firefighters gathered in front of Tehran city hall on Wednesday in protest to the indifference of authorities to their problems.

They also urged the resignation of Tehran’s Fire Department chief and vowed to continue similar rallies until their demands are met.

Last week, thousands of teachers held their fourth round of nationwide protests in more than 50 Iranian cities to demand better salaries and the release of their colleagues detained in earlier demonstrations.

Authorities, who have shown little interest in raising salaries, arrested Mohammad Taghi Fallahi, the head of Iran’s teachers’ union to serve his six-month sentence for organizing the protests.

Workers and employees from various economic sectors are holding regular protest rallies or strikes to demand better work conditions and salaries.

Last week, hundreds of staff members from Iran’s hardliner judiciary department took to the streets in several cities, in what was an unprecedented development.

Food prices have risen by more than 60 percent in recent months, on top of high inflation in the previous three years. Government figures show that prices for 83 percent of basic food staples have reached a critical level. People living on salaries have cut back on nutritious food, such as meat, fruits and dairy products.
