Mexican government response

On May 31, 2021, 250 National Guard troops and 60 agents of the Attorney General's Office were sent to the Teotihuacán site to seize parcels of land intended for illegal construction and to forcibly stop further destruction of historical sites. The National Institute of Anthropology and History (INAH) had suspended authorization for those projects in March, yet construction work with heavy machinery and looting of artifacts had continued. The seizure of the land came a week after the International Council on Monuments and Sites (ICOMOS) warned that Teotihuacán was at risk of losing its UNESCO World Heritage designation.
