Protests in Greece mark two years since deadly train crash

In Athens today, massive demonstrations hit fever pitch as protesters pummeled police with rocks and gasoline bombs outside the Greek parliament. Protests and vigils across the country Friday marked the two-year anniversary of a deadly train crash that killed 57 people. Since then, anger has grown out of what many Greeks see as a lack of accountability on the part of the current government in response to the tragedy.
