Mass Chlorine Gas Incident: More Than 600 Individuals Hospitalized in Iraqi Hospitals - Multiple pilgrims hospitalized due to chlorine gas leak in Iraq, affecting over 600 individuals
In a tragic turn of events, a chlorine gas leak on August 10, 2025, along the route between the Shiite holy cities of Najaf and Karbala, affected over 600 pilgrims who were making their way to Karbala for the Arbaeen commemoration[1][2][3]. This religious event, marking the 40-day mourning for Imam Hussein, the grandson of Prophet Muhammad, is one of the largest religious gatherings in the world[1][2][3].
The chlorine gas leak, caused by a technical malfunction at a water treatment facility, exposed the pilgrims to a highly irritant and corrosive substance[1][3][4][5]. When inhaled, chlorine gas reacts with moisture in the respiratory tract, forming acids that damage tissue and cause inflammation[2]. Symptoms of exposure can include burning sensations, eye redness, watering eyes, sore throat, coughing, choking, and difficulty breathing[2].
Fortunately, the affected individuals received prompt medical attention, and ambulances and civil defense teams quickly responded, transporting them to hospitals[1][5]. Most of those exposed recovered after receiving medical care[1][3]. The Ministry of Health in Iraq reported 621 cases of shortness of breath following the incident[1][2][3].
It is important to note that the Arbaeen commemoration in Karbala is not organised by the Ministry of Health, but the city of Karbala is the destination for millions of Shia pilgrims every year[6]. The city is also the burial place of Imam Hussein and his brother, Abbas[7].
The chlorine gas leak occurred near a water station, but the exact location was not specified in the article[1][3]. The incident underscores ongoing safety and infrastructure challenges in Iraq, particularly in the context of the country's aging infrastructure and lax safety standards, partly from decades of conflict and corruption[3][4].
The security forces responsible for pilgrim protection made the announcement about the chlorine gas leak[1]. All the affected individuals received necessary treatment and were discharged from the hospital[1][3]. The health issues caused by the chlorine gas leak have been addressed, and there were no reported fatalities[1][3].
