KHARTOUM, Sudan (AP) — The teenage boy’s hands and legs were shackled to the anti-aircraft gun mounted on a pickup as Sudanese warplanes attacked. He said dozens of foreign mercenaries were at the base, described as Colombians by the RSF fighters there. They told RSF fighters to bind the children to the weapons so they couldn’t escape, he said. The Colombian government said it has no official information confirming allegations that Colombians recruited or trained child soldiers in Sudan. RSF fighters shot at him as punishment, wounding his foot.
