A powerful car bomb exploded in front of the USO club in Calata San Marco which caused the deaths of five people, including an American, and injuries to 15 others.
The attack was perpetrated by a Japanese Red Army (JRA) member and came on the second anniversary of the 1986 United States bombing of Libya.
Police later identified Junzo Okudaira as the main suspect, a member of the far-left Japanese Red Army (JRA) with links to groups in Lebanon.
Okudaira was already wanted in Italy over a rocket and bomb attack against the American and British embassies in Rome in 1987, where nobody was hurt.
[4] A few days before the bomb attack, JRA member Yū Kikumura was arrested in the United States.
