Tehran, Iran - November 26, 2025 Tehran has imposed widespread closures as hazardous air pollution blankets the Iranian capital. Authorities announced that all schools, universities, and educational centers will suspend in-person attendance and shift to remote learning. Government offices have also moved to remote work in an effort to reduce traffic and limit exposure to the toxic smog. The city has been struggling with worsening air quality driven by vehicle emissions, industrial output, and stagnant weather conditions that trap pollutants over the metropolis. Officials warn that pollution levels have reached dangerous thresholds, posing a serious health risk — especially to children, the elderly, and people with respiratory illnesses.
