In Mexico, authorities are investigating a series of small bombings in Mexico City. They exploded on Monday morning at Mexico’s top electoral court, the headquarters of the PRI party and a bank. No injuries were reported. The Associated Press reports that a coalition of five leftist groups claimed responsibility for the homemade bombs. In a statement the groups stated “Our political-military action is a response to our determination to reply with revolutionary violence to the violence unleashed by the lords of power and money.”
