We recently completed a short unit based on the events in Iguala, Mexico and the students from Ayotzinapa. Below is a link to a shared file, which contains a reading and several other resources. Adapt and use as you’d like. This topic is so large, current and constantly evolving that every Spanish teacher’s approach will be different.
Some of the files are source documents with links to various resources.
There are also some great resources at this page also.
