On 26 December 1987, a bomb attack on a United Service Organizations (USO) club in Barcelona, Spain killed an American sailor and injured nine others.
[citation needed] Both Terra Lliure and Catalan Red Liberation Army (ERCA) claimed responsibility.
Residents claimed that anti-American slogans and graffiti near the bar at the time suggested the incident was linked to the extension of the Spain-United States military treaty (Pact of Madrid), which was first signed during the tenure of caudillo Francisco Franco in 1953.
[1][2] Terra Lliure had previously claimed responsibility for an attack on an American consulate in Barcelona in October, which wounded eight sailors.
[3] A woman claiming to be from ERCA took responsibility "against an establishment of the Yankee war marines" in a call to news agency EFE.
