the newspaper "la tercera" published on its front page a photograph showing prisoners at the quiriquina island camp who had been captured during the fighting in concepción. the photograph's caption stated that some of the detained were local leaders of the "unidad popular" while others were "extremists who had attacked the armed forces with firearms". the photo is reproduced in docuscanner. this is consistent with reports in newspapers and broadcasts in concepción about the activities of the armed forces, which mentioned clashes with "extremists" on several occasions from 11 to 14 september. nocturnal skirmishes took place around the hotel alonso de ercilla in colo colo and san martín street, one block away from the army and military police administrative headquarters. a recently published testimony about the clashes in concepcion offers several plausible explanations for the reticence of witnesses to these actions.
