A long-standing territorial dispute between the municipalities of Ixchiguán and Tajumulco in the San Marcos department of Guatemala continues to cause violence. The conflict, rooted in unclear border definitions since 1933, has evolved from disputes over land and water into violence involving organized crime and poppy cultivation.

On October 30, 2026, two members of the Guatemalan Army, an officer and a soldier, were injured while performing surveillance duties at a high-altitude observation post. The Army attributed the injuries to clashes between illegal armed groups. Both personnel were reported to be in stable condition.

By November 7, 2026, the instability resulted in further civilian casualties. A child was wounded by gunfire in the El Rodeo village after being struck in the shoulder during an intensification of shooting from the mountains separating the two municipalities.
