ATHENS - Previously unknown extremists have claimed responsibility for planting a small bomb on the Athens metro in February, police said, in a sign that far-left groups are increasingly turning to violence to protest against economic austerity.
At the time, a train driver found the homemade device hidden in a backpack on an empty subway train. It contained two small gas canisters, 1.5 liters of gasoline, a timer, wires and batteries, but it was not primed to explode.
A statement claiming responsibility was posted on a website on Sunday by a group calling itself the "February 12th Movement." Police said details in the seven-page letter suggested the claim was genuine.
