Tehran, Iran, Dec. 31 – Some 200 workers from the Miral glass factory held a demonstration and set fire to tires south of Tehran Saturday morning in protest to their employers’ refusal to pay their overdue salaries.

The glass workers gathered outside the site of their factory near the Tehran-Saveh Highway. They complained that despite five to 25 years of service, many of the workers had not received their wages for the past 10 months. State Security Forces were called in when the protestors blocked traffic on the road by burning tires.
