Anti-terrorism police in northern Italy have seized an air-to-air missile and other sophisticated weapons during raids on far-right extremist groups.
Three people were arrested – two of them near Forli airport, the BBC reported.
Neo-Nazi propaganda was also seized, in raids in several cities.
Italian media say the raids were part of an investigation into Italian far-right help for Russian-backed forces in eastern Ukraine.
The missile is reported to be Qatari.
The Turin special police force, called Digos, led the operations, assisted by police in Milan, Varese, Forli and Novara.
Italian media named those arrested as Fabio Del Bergiolo, 50, an Italian ex-customs officer and far-right Forza Nuova party activist; Alessandro Monti, 42, a Swiss national; and Fabio Bernardi, 51, also Italian.
On July 3, a court in Genoa jailed three men who were found guilty of fighting alongside the Russian-backed forces who control a large swathe of Ukraine's Donetsk and Luhansk regions.
Two of them – Italian Antonio Cataldo and Albanian-born Olsi Krutani – got terms of two years and eight months. The third, Moldovan citizen Vladimir Vrbitchii, got one year and four months.
