High ranking officers of the anti-terrorist unit estimate the attack against the French Embassy, Thursday morning, was a well organised operation that was carried out by experienced members of an armed group. So far authorities have not definitively concluded as to which particular group could be behind the attack, but after examining all the data collected are leaning towards a group called “Group of Popular Fighters”. The fact that the two motorcycle riders chose to strike in such a brazen fashion in one of the most heavily guarded areas in Athens, located across the Parliament and in close proximity to both the Greek PM’s house and the Foreign Ministry was a symbolic move, according to the anti-terrorist unit. “The upcoming visit of Obama and the November 17 Polytechnic anniversary present the perfect stage for armed groups to intensify their actions and make a show of force”, an officer told Protothema.gr. He continued by stressing that the fact the culprits hit a target surveyed with so many cameras and guarded by a riot unit illustrated they were not concerned about concealing their identity but of making a statement. The footage examined showed the two terrorists managed to hide behind a moving bus to avoid detection by the riot unit police before throwing the hand grenade against the French Embassy. Meanwhile, following the attack, Greek police headquarters have been working on a contingency plan for security measures on the visit of US President Barack Obama, who is expected to arrive in Athens next week. Police are waiting for a proclamation to be released of a group assuming responsibility for the attack.
