A wave of cartel-related violence in Mexico’s state of Guerrero is forcing between 800 and 1,000 families to flee their homes in a mountainous rural area, according to community and human rights groups. The violence begins on Wednesday, with groups identified in reporting as members of Los Ardillos launching attacks on local communities.

Accounts describe sustained assaults on residents in the region, with sources citing the use of weapons including powerful arms and handmade explosive devices. ABC News reports that some explosives are launched from drones, while other details of the attacks are described generally as armed aggression against communities.

The displaced families remain in the mountains or move to safer areas as they try to avoid further attacks. The reports characterize the incident as part of an ongoing criminal conflict in central Mexico, with local residents and civil society groups drawing attention to the humanitarian impact and urging responses to protect civilians.
