Colombia Farc rebels kill four hostages as one escapes
Left-wing Farc rebels in Colombia have shot dead four hostages, the authorities say.
The captives - all members of the security forces - were killed as troops approached the camp where they were held in the southern region of Caqueta.
All had been held for more than 12 years after being captured in rebel attacks.
The men have been named as police Col Edgar Duarte Valero, police Major Elkin Hernandez Rivas, policeman Alvaro Moreno, and army Sgt Jose Martinez Estrada.
Hours after their bodies were discovered, a fifth hostage was found alive. Will Grant reports.
