Comandos Autónomos Anticapitalistas

The Comandos Autónomos Anticapitalistas (CAA or CCAA) (Basque: Komando Autonomo Antikapitalistak; "Autonomous Anticapitalist Commandos") were a Basque armed group in Spain with Autonomist Marxist politics, defined as an anarchistic breakaway of ETA.

[citation needed] The commandos who killed Casas were called Mendeku (revenge in Basque language).

Soon after, one of the few operating CAA commandos was ambushed by the Guardia Civil at the bay of Pasaia, killing four – all but one.

The police tried to link another group they called Mendeku to the CAA, after an attack against the headquarters of the Spanish Socialist Workers' Party in Portugalete in 1987 where two people died.

a paramilitary group including former Francoist officers which used public funds and participated in the Spanish state's war on terrorism was allegedly involved in the ambush.
