In Constitution Square, Athens, tensions escalated into clashes after a significant rally commemorating the third anniversary of the Tembi train disaster. Thousands of individuals participated peacefully in the event, which aimed to honor the memory of the victims and call for accountability regarding the tragedy. However, following the rally's conclusion, groups of people reportedly began engaging in confrontations, prompting a police response.

Strong police forces were deployed in the area, as reported by the television station SKAI, who noted that law enforcement used chemical agents to control the situation. The police took preventative measures, resulting in at least 128 detentions during the course of the gathering, with three individuals being arrested for carrying flares and a maritime flare gun. Despite these incidents, reports indicate that the surrounding area has since seen a normalization of control by law enforcement.

The events highlight ongoing public sentiments regarding the Tembi tragedy—a disastrous train collision that occurred three years ago—and reflect broader societal frustrations over safety and accountability in Greece's transport system. The government may face increased pressure to address concerns raised by the public during such demonstrative events, especially as the anniversary of the tragedy serves as a poignant reminder of the need for systemic changes to ensure passenger safety in the future.
