When it exploded, it killed two drivers and wounded six other civilians. In Arauquita (Arauca) on 17 and 19 February, explosions which killed one civilian and wounded others were attributed by the authorities to members of the FARC-EP. In Pasto (Nariño) on 20 July, two bombs were detonated by members of the FARC-EP in public buildings, killing one person and wounding another. D. Torture and other infringements against personal dignity 59. During 2006, the Office learned of cases of torture attributed to the FARC-EP. In Riosucio (Chocó) in July, the corpses of 12 sawmill workers who had been killed by members of this armed group bore signs of having been tortured with machete blows before they died. In Mocoa (Putumayo) on 11 September, FARC-EP guerrillas arrested a cameraman who was covering the demobilization of a paramilitary group and accused him of collaborating with the paramilitaries. They then made him dig a grave and kneel down beside it. 60. The OHCHR Office also learned of cases of torture attributed to army personnel. According to the Attorney-General’s Office, the body of a person killed at Copacabana (Antioquia) on 13 February by members of the Fourth Brigade showed signs of having been tortured. E. Hostage-taking 61. The taking of hostages continues to be a common practice among the illegal armed groups, especially the FARC-EP. On 12 July in Riosucio (Chocó), members of this guerrilla group kidnapped 112 Afro-Colombian sawmill workers. In Santa Fe de Antioquia on 26 June, FARC-EP guerrillas took three people hostage and fired at short range at two of them, killing one, when they found themselves surrounded by soldiers. In Ricaurte (Nariño) on 24 September, men from the FARC-EP seized the governor of the Magui indigenous reserve and his nephew; their whereabouts remain unknown. 62. In Dosquebradas (Risaralda) on 27 April, the authorities attributed to FARC-EP guerrillas the interception of a vehicle in which Ms. Liliana Gaviria Trujillo, the sister of ex-President César Gaviria Trujillo, was travelling. They intended to take her hostage, but both she and her escort were shot and killed by the attackers. 63. The Office received information that, near Teteyé in Puerto Asís (Putumayo) on 21 June, members of the FARC-EP took hostage members of a mission comprising doctors, nurses and auxiliary workers from the First-Level Hospital in that municipality. Later 12 of those seized were released, but the guerrillas continued to hold 1 of them whose whereabouts are unknown. 64. Further taking of hostages was attributed to the ELN and the EPL. On 2 May in Salahonda (Nariño), ELN guerrillas took hostage Sectional Prosecutor No. 48, who was later rescued by the army. On 15 January in Anserma (Caldas), members of the ELN took hostage a university student, whose body was found by the authorities on 16 September in an open grave in the countryside.
