The Australian grandfather of a seven-year-old boy photographed by his father holding up the severed head of a Syrian soldier is begging his government to bring the boy and his siblings home.
"Can't the government do something to pull these kids away from that man?" Peter Nettleton told the Daily Telegraph.
"I'm scared for the children," he said. "What life are they going to have now?"
On Monday, news reports surfaced after ISIS fighter and convicted terrorist Khaled Sharrouf posted a photo to Twitter of his son using two hands to hold up the severed head of a soldier, with the comment: "That's my boy!"
Nettleton said he thought his daughter Tara and son-in-law Sharrouf had taken their five children - two girls and three boys - to Malaysia while he fought in Syria.
Nettleton, who is estranged from his daughter, said Tara and Sharrouf were teenage sweethearts and she converted to Islam for him. He does not know his grandchildren.
