What major political unrest has racked Guatemala in recent weeks?

I’ve heard about a lot of problems occurring in Honduras, and other Latin American countries. One that really interests me, however, is that of Guatemala. However, I’ve been unable to put a finger on just what’s happened. Can anyone fill me in on the most recent political problems in Guatemala, or at least give me an idea of where to look?

The most pressing political problem is the accusations of murder against the current president, but that story is several months old, and has not been resolved.
