The intensifying assault by the criminal group Los Ardillos on Indigenous Nahua communities in Guerrero’s Montaña Baja region has forced an estimated 800 to 1,000 families to abandon their villages, according to the National Indigenous Congress. The government in Mexico City acknowledges only 96 displaced individuals, a figure that local organisations dismiss as a drastic undercount. Attacks include drone bombings and sustained gunfire, with reports of at least four fatalities and dozens more missing. The scale of the crisis, unfolding since early May, has drawn comparisons to the darkest episodes of Mexico’s drug war.

Viewed from Mexico City, the administration of President Claudia Sheinbaum has prioritised a policy of non-confrontation. Security Secretary Omar García Harfuch confirmed that federal forces—including the National Guard and the army—are present in the area but have been instructed to avoid direct engagement with the armed groups. Interior Secretary Rosa Icela Rodríguez has travelled to Chilapa to negotiate the removal of roadblocks and to arrange medical evacuations. Critics, including the Congress’s spokesperson Carlos González García, argue that this restraint amounts to abandonment, leaving communities defenceless against well-armed cartels that operate with near-impunity in the mountainous terrain.

In a sign of deep desperation, displaced Indigenous women have recorded video messages addressed directly to U.S. President Donald Trump, pleading for helicopter rescues and accusing President Sheinbaum of ignoring their plight. “We are being killed, our houses are being burned,” one woman said, her face covered. The appeal underscores a profound erosion of trust in federal institutions. Washington has not publicly responded, but analysts in London note that such cross-border pleas risk complicating bilateral security cooperation, particularly as Mexico has consistently rejected foreign intervention in its internal affairs.

The immediate trigger for the violence appears to be a feud between Los Ardillos and a rival group, Los Tlacos, for control of drug-trafficking routes and extortion rackets in the Sierra. Civilians are caught in the crossfire. The Sheinbaum government’s strategy—dialogue over force—may be intended to avoid inflaming a wider insurgency, but it has left residents of Autlán de Tula, Acatlán, and Alcozacán in a state of siege. With no ceasefire in sight, and the security apparatus stretched thin across Guerrero, the region risks becoming a permanent no-go zone for the state, a grim precedent for the president’s broader pledge to pacify Mexico through social programmes rather than military action.
