From daily The Morning Star in Britain:
Chile: 10 former soldiers charged with Victor Jara murder
Friday 24th July 2015
The charges, announced late on Wednesday by Judge Miguel Vazquez, include the murder and kidnapping of Mr Jara and former military police director Littre Quiroga Carvajal.
Mr Jara played a borrowed guitar and sang songs for the detainees until soldiers broke his hands. He kept singing until his death.
The announcement of the charges against the officers came a day after seven former soldiers — two former officers and five former non-commissioned officers — were arrested for burning a teenage photographer to death during 1986 protests against Pinochet’s regime.
Soldiers doused Rodrigo Rojas, 19, and Carmen Quintana, 18, with petrol and set them on fire during a street demonstration.
Ms Quintana thanked a former soldier, identified as Fernando Guzman, for coming forward with new information on the case.
She said the soldiers involved were also victims of the dictatorship because they had received death threats to intimidate them into keeping silent.
