Nuclei Armati Comunista is no longer active.

A group calling itself the "Nuclei Communist Combatants" (NCC) claimed responsibility for a January 10th, 1994 bombing outside the NATO Defense College in Rome.  The bomb, a crude 3-4 kg device, exploded around 1:00AM when streets were deserted.  Although the bomb caused some structural damage to the college, there were no injuries.  The attack was linked to a NATO summit that was scheduled to begin in Rome the same day.  Although Italian authorities doubt the veracity of NCC's claim, no other group claimed responsibility, and no arrests were ever made in connection with the incident.

It is unclear whether the "Nuclei Communist Combatants" group was an actual terrorist organization.  In any case, the NCC has not claimed responsibility for further attacks and can be presumed inactive.

The "Nuclei for Promoting Total Catastrophe" is one of many Greek anarchist groups that use arson as a primary weapon.  On February 15, 2004 the NPTC claimed responsibility for setting fire to a mobile library, which belonged to the Regional Union of Municipalities and Communities of the Ioannina Prefect.  The library was damaged but not destroyed in the attack.  In their claim of responsibility, the group decried the Greek education system.  They wrote, "The education system is operating according to the system's guidelines. Education and culture churn out only miserable extras in this theater of absurdity. Our sole demand is the total destruction of the system. Our fire will burn until we walk on its rubble."

In nearly all Greek arson cases such as this one, the attacks were perpetrated by loosely affiliated individuals, and not highly organized terrorist organizations. There is no reason to believe that the "Nuclei for Promoting Total Catastrophe" is an exception to this rule, and it is unlikely that the group will carry out any more attacks.
