The death of two anarchists while allegedly preparing an explosive device has drawn intense attention to Italy’s domestic security landscape.
Over the night of March 19–20, a blast occurred in an abandoned country house in Rome’s Parco degli Acquedotti, a large public park in the southeastern outskirts of the city famous for its ancient Roman aqueducts.
The explosion collapsed the building, killing both individuals later found in the rubble.
Authorities initially treated the incident as a structural collapse, but forensic analysis soon confirmed it was caused by the accidental detonation of an improvised explosive device being constructed inside the derelict farmhouse.
Police identified the victims through distinctive tattoos as Sara Ardizzone (35) and Alessandro Mercogliano (53), both known to investigators for their involvement in anarchist circles linked to Italian insurrectionary activism.
Both had prior brushes with the law: Mercogliano was previously convicted in connection with a major anti‑state network probe; Ardizzone had faced investigations for incitement and other charges, once describing herself in court as an “enemy of the state”.
Authorities also confirmed that both were connected to anarchist networks associated with Alfredo Cospito, a high-profile Italian anarchist currently serving a high-security prison sentence.
Italian authorities are now investigating how the two intended to use the device they were constructing and are working to determine whether their potential attack might have been co-ordinated with other recent episodes of far-left anarchist violence in Italy.
In particular, authorities are examining potential links between the two and a recent suspected attack on the national rail network, described as “serious sabotage” amid the opening of the Milano‑Cortina Winter Olympics.
On February 7, multiple incidents were reported around the Bologna rail hub and nearby lines, including fires at signalling equipment, severed electrical cables and the discovery of a rudimentary explosive device, causing widespread disruption.
Authorities treated these as deliberate acts rather than technical failures. A statement later appeared on an anarchist web portal linking the attacks to opposition to the Olympics and framing them as a protest against government policy.
In response to the two deaths, Italy’s Strategic Anti‑Terrorism Analysis Committee convened at the interior ministry to assess the implications of these events,. It examined whether the device in the Rome blast was intended for a violent attack, whether others were involved and potential links to the recent sabotage of the rail network.
The case highlights an emerging concern over co-ordinated far-left, specifically anarchist militancy targeting both symbolic and critical infrastructure, suggesting these incidents may form part of a broader operational pattern.
In recent months, the Italian Government has introduced a package of “law and order” reforms targeting far-left violence. It has granted police expanded powers over demonstrations, pre-emptive detention, stricter control of knives and weapons and faster eviction procedures for illegally occupied buildings.
These measures were largely motivated by repeated street violence by far-left activists rather than anarchist explosive attacks.
Following the deaths of Ardizzone and Mercogliano, some observers are now questioning whether specific legal measures should be developed to address this type of threat.
