Installation of military base in Morococha

In the last months of 1989, after a series of dynamite attacks by the PCP-SL against Centromín Perú's facilities in Morococha, a military base was installed in the mining camp. The installation of this base occurred shortly after the formation of a defensive brigade by the workers, whose purpose was to protect the integrity of the workers from aggressions by the PCP-SL or any other violent group. The members of the brigade never had any confrontations with the Senderistas due to the rapid installation of the military base. After its installation, the military began to carry out violent raids to the homes of all the workers with the objective of capturing suspected subversive elements.
