Oil workers join protests in Iran over Mahsa Amini's death

Workers at refineries crucial for Iran's oil and natural gas production protested Monday over the death of a 22-year-old woman, online videos appeared to show, escalating the crisis faced by Tehran.

The demonstrations in Abadan and Asaluyeh mark the first time the unrest surrounding the death of Mahsa Amini threatened the industry crucial to the coffers of Iran's long-sanctioned theocratic government.

While it remains unclear if other workers will follow, the protests come as demonstrations rage on in cities, towns and villages across Iran over the Sept. 16 death of Amini after her arrest by the country's morality police in Tehran. Early on Monday, the sound of apparent gunshots and explosions echoed through the streets of a city in western Iran, while security forces reportedly killed one man in a nearby village, activists said.
