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 saw another child chained to the steering wheel. As their captors sought cover, the terrified children were ordered to stay and shoot down the jets over the capital, Khartoum. If they tried to flee, they’d be killed by their captors – if the planes didn’t get them first.
