Authorities in Athens are intensifying their investigation into a bomb explosion that killed a 36-year-old man and severely injured a 33-year-old woman. The explosion, described as a ‘monstrous bomb,’ is believed to be linked to anti-authoritarian groups aiming to escalate their activities to a new level of terrorism. Evidence from the site suggests the attackers had considerable expertise in explosive manufacturing. A 31-year-old suspect has been arrested, denying involvement, while a 30-year-old woman connected to the case remains in the Netherlands. Police are examining various digital clues that could reveal further connections and intended targets.
