Methane Gas Exposure Claims Lives of 12 Turkish Soldiers
12 Turkish Soldiers Martyred by Methane Gas During Cave Operation
In a deeply tragic development, the Ministry of National Defense (MSB) of Turkey has confirmed the deaths of 12 brave soldiers who were martyred after being exposed to methane gas during a counterterrorism operation in northern Iraq.

The incident occurred on July 6, 2025, during Operation Claw-Lock, where Turkish forces were carrying out a search and screening operation at an altitude of 852 meters in a cave used by members of a separatist terrorist organization. According to the Ministry, the soldiers were conducting an anti-terror sweep when they encountered toxic levels of methane gas within the confined underground space.
Initially, several soldiers were affected by the gas exposure, with 8 fatalities confirmed. Sadly, the number has now risen to 12 after four more succumbed to the effects of the poisoning. The operation was part of Turkeyβs broader efforts to neutralize terrorist threats along its borders and eliminate hideouts used by militants.

In an official statement posted on the MSB’s social media account, the Ministry expressed its profound sorrow:
βOn July 6, 2025, during a search and screening operation at Hill 852 in the Operation Claw-Lock region, four more of our heroic comrades were martyred due to methane gas exposure in a cave used by a separatist terrorist organization. This brings the total number of our martyrs to 12.β
National Defense Minister Yasar Guler traveled to the operation zone to oversee the inspection, conduct audits, and participate in farewell ceremonies for the fallen heroes. His presence underlined the gravity of the incident and the nation’s commitment to honoring its soldiers.
The Turkish Armed Forces and the entire nation are mourning this significant loss. Thoughts and prayers have been extended to the families of the deceased, as well as to the wounded, whose recovery is being closely monitored.
Methane gas is a silent killer in confined spaces such as caves, especially when there is no adequate ventilation. Experts have raised concerns in the past about the hidden dangers of cave operations, particularly in conflict zones where natural and man-made hazards converge.

The Turkish government has vowed to continue its anti-terror operations with renewed focus, honoring the sacrifice of those who gave their lives in service to their nation. This tragic event is a stark reminder of the risks faced by soldiers even in seemingly routine field operations.
Turkeyβs military has intensified counterterrorism operations in northern Iraq in recent years under various operations, including Claw-Tiger and Claw-Eagle, targeting PKK militant strongholds.
