Police raids target anarchist network after deadly Rome blast

Rome – Italian anti terror police have launched a series of coordinated raids across the capital as investigators widen their probe into a suspected anarchist network following a deadly explosion that has raised national security concerns.

Officers from the Digos carried out five searches overnight in properties linked to anarchist circles, seizing materials now under forensic examination. Authorities said that, at this stage, the items do not appear to be directly connected to the blast, but may prove useful in reconstructing a broader network.

The operation follows an explosion at the Parco degli Acquedotti, where Alessandro Mercogliano and Sara Ardizzone were killed when a derelict farmhouse collapsed. Investigators believe the pair were assembling an improvised explosive device intended for an imminent attack.

Both individuals were reportedly known to authorities and linked to anarchist circles associated with Alfredo Cospito, whose detention under the 41-bis prison regime has become a focal point for militant activism. Early forensic findings support the bomb-making hypothesis, with one of the victims believed to have been handling the device at the moment of detonation.

The investigation, coordinated by prosecutors in Rome, has now expanded beyond the immediate घटना to examine the wider anarchist milieu. Detectives are working to map the pair’s contacts and determine whether they acted independently or as part of a more structured and organised network. Particular attention is being paid to the possible existence of a supply chain that may have provided the materials used to assemble the device, as well as to the suspects’ recent movements and communications.

Forensic experts are also analysing the nature of the explosive. One line of inquiry is whether the materials used were easily obtainable or derived from more specialised, industrial sources. The reported presence of nails among the debris suggests the device may have been designed to maximise harm, raising concerns about a potential escalation beyond symbolic or demonstrative actions typically associated with segments of the anarchist movement.

Authorities are simultaneously attempting to identify the intended target. Several hypotheses are under consideration, including infrastructure such as the high-speed rail network, security or law enforcement facilities, and sites linked to broader anti-government or anti-globalisation causes. Investigators have not ruled out a connection with recent acts of sabotage targeting Italy’s rail system, particularly in the context of heightened security concerns ahead of the Milan-Cortina 2026 Winter Olympics.

The case has prompted a high level institutional response. Interior Minister Matteo Piantedosi has convened a meeting of the Strategic Anti-Terrorism Analysis Committee at the Interior Ministry to assess potential threats linked to anarchist activity.

As the inquiry unfolds, officials are seeking to determine whether the incident represents an isolated episode or a sign of a broader shift in tactics within Italy’s fragmented anarchist landscape, with growing concern over the possibility of more coordinated and potentially lethal actions.
