The Turin-Lyon high-speed rail project in Italy’s Val di Susa has come under renewed scrutiny after a violent attack on a construction site near Chiomonte, according to Il Fatto Quotidiano. The incident, which occurred on July 27, 2026, left approximately one million euros in damage.
Prosecutors have requested prison sentences for two individuals detained in connection with the assault, ANSA reports. A police officer involved in the response described the attackers as emerging from the woods, telling Avvenire that officers “defended themselves as best they could.”
The attack has reopened fractures within Italy’s broad left-wing coalition, according to La Stampa. Pro-Tav supporters are planning a counter-demonstration, while the No-Tav movement continues to oppose the project on environmental and cost grounds.
Il Fatto Quotidiano frames the incident not merely as a million-euro setback but as evidence of the failure of a project that has already cost €16 billion. The outlet argues that the violence underscores the deep and unresolved opposition to the tunnel, which is designed to connect Turin with Lyon, France.

Enrico Borghi, a politician interviewed by Radio Radicale on the day of the attack, offered his perspective on the unrest in the valley. The interview did not provide specific details on his position.
The attack is the latest escalation in a long-running conflict that has seen protests, legal battles, and occasional violence since the project’s inception. Observers are now watching whether the renewed tensions will prompt a shift in government policy or further delay the already controversial infrastructure work.
