Guatemala has deployed more than 2,000 soldiers to its border with Mexico in an effort to combat drug trafficking across the border.

The powerful military force was deployed on Tuesday in the mountainous provinces of San Marcos and Huehuetenango, home mainly to indigenous Mayan tribes. In these degraded areas, many residents eke out a living by growing marijuana and poppies. These crops lead to the production of opium and its derivatives (morphine, heroin).

Across the border, the southern Mexican state of Chiapas is rocked by clashes between the Sinaloa and New Generation Jalisco cartels. The wave of violence has caused food shortages and power outages, forcing many shops to lock down and residents to seek supplies from neighboring Guatemala.

Illegal crossings on Guatemala’s border with Mexico – which stretches for about 1,000 kilometers – are linked to the trafficking of drugs and irregular migrants mainly destined for the US.
