A/HRC/60/18 it became operational, the Mechanism has maintained two distinct investigative teams: one dedicated to crimes against the Rohingya population (both historical and ongoing crimes) and another focused on examining crimes committed against other groups, including those committed since the military coup in 2021. A. Investigating post-coup crimes 8. Since the military coup in February 2021, the Mechanism has collected and analysed substantial evidence of serious international crimes committed across the country. During the reporting period, the number of such crimes escalated significantly. The Mechanism has been collecting new reports of the imprisonment of thousands of individuals without fundamental due process; indiscriminate air strikes; civilian deaths in artillery and drone attacks; the burning or destruction of homes, hospitals, schools and places of worship; and torture and abuse committed against those in detention, including sexual violence. These investigations have resulted in various analytical reports establishing and demonstrating the contextual elements of crimes against humanity and war crimes, which are available for sharing with investigative, prosecutorial and judicial authorities. Crimes related to ongoing armed conflicts 9. During the reporting period, the Mechanism gathered and examined large quantities of evidence of crimes connected to ongoing armed conflicts across Myanmar, including in Chin, Kachin, Kayah, Kayin, Rakhine and Shan States and in Sagaing and Magway Regions. Investigations into past and new incidents include: (a) indiscriminate or intentional aerial and artillery attacks against civilians and/or civilian objects; (b) killings of civilians or combatants detained during operations; and (c) sexual and gender-based crimes. 10. More specifically, the Mechanism continued to secure and assess volumes of material regarding the escalating use of air strike attacks in various locations throughout the country. As aerial attacks impacting on civilians and civilian objects continued to escalate, the Mechanism intensified its investigations into those incidents. The Mechanism sought evidence of whether the strikes were targeted at military objectives or were primarily or disproportionately targeted at civilians. Among the incidents that the Mechanism has examined are attacks on internally displaced persons’ camps and attacks on schools, religious buildings and health facilities in Kayah State. These incidents have caused large numbers of civilian casualties and significant destruction of civilian infrastructure, without there being any apparent military target in the vicinity of the areas attacked. The Mechanism is analysing the composition of the Myanmar Air Force and its chain of command in order to identify the perpetrators involved in the air strike attacks. In this context, the Mechanism also continues to evaluate information on supply chains for the weapons and equipment used in the air strikes. Moreover, the Mechanism has been examining reports on the alleged use of chemical weapons by the Myanmar military. 11. The Mechanism has received testimony from civilians in conflict-affected areas, many of whom have been displaced several times. They have described the mental terror caused by the sounds of planes, helicopters and drones overhead and the constant fear of being attacked. Children have been particularly traumatized. The Mechanism has gathered credible information on the increased use of drones and paramotors, in addition to jet fighters and helicopter gunships, to deliver deadly munitions during air strikes against civilians. 12. Despite the devastation caused by the earthquake on 28 March 2025, the military continued to conduct air strikes in the aftermath. The air strikes continued even after the military declared a ceasefire to assertedly facilitate rescue and humanitarian relief. The Mechanism is closely tracking reports of humanitarian aid being blocked or confiscated in areas affected by the earthquake. The Mechanism has also assembled credible evidence of other instances of humanitarian assistance being blocked, such as in Sittwe in Rakhine State. 13. During the reporting period, the volume of evidence detailing killings of civilians or combatants detained during operations increased. The Mechanism obtained evidence of such killings perpetrated by the security forces of Myanmar, affiliated militias and opposition armed groups. Credible information indicates that captured soldiers, combatants and civilians GE.25-10777 5
