BOGOTA — Four indigenous children who were missing for more than five weeks in Colombia’s southern jungle, after surviving a plane crash which killed their mother, are in an “acceptable” state of health, the government said on Saturday. “In general the boy and the girls are in an acceptable state. “We never expected to find them so well.”Velasquez recognized the eldest of the siblings, a 13-year-old girl, for her bravery. The youngest of the children turned one while in the jungle, while her brother had his fifth birthday, he said. Three adults, including the pilot and the children’s mother, died in the crash and their bodies were found inside the plane.
