Greece: Bomb at Citibank branch

Anthee Carassava reports in The New York Times :

A makeshift bomb exploded Monday outside a Citibank branch in Athens, gutting the ground floor of the two-story building but causing no injuries. There was no immediate claim of responsibility, but police and counterterrorism officials said the attack bore the earmarks of the Revolutionary Struggle, a leftist militant group best known for firing a rocket-propelled grenade into the American Embassy in Athens in 2007. The police defused a bomb outside Citibank's administrative headquarters in northern Athens a month ago.
