Riots broke out in front of Peru's Congress in Lima late on October 15th, 2025, resulting in fires, the use of tear gas, and at least one police officer injured by a thrown stone. The demonstration, which commenced peacefully in Plaza San MartÃn, escalated into violent confrontations. The incidents occurred within the reporting window between 11:36 PM UTC on October 15th and 2:36 AM UTC on October 16th. Images circulating on social media show objects burning directly in front of the legislative building. The injured police officer was reportedly struck by a stone during the clashes, according to reports from MundoEConflicto and AlertaNews24. Separately, in a development impacting fiscal policy, the TCU (Tribunal Constitucional del Perú) suspended a decision that would have compelled the government to pursue a fiscal target. This ruling, announced prior to the protests' escalation, relates to government financial obligations. The protest began earlier in the day as a youth march, but devolved into unrest as the evening progressed. Details on the specific demands of the protesters or the organization behind the march were not immediately available in the provided sources.
