'That's my child', Brit dad identifies IS child jihadist as his and Sally Jones's son

London: Two days after Islamic State terrorists released a horrific video showing five minor boys shooting prisoners in Syria, a Briton has identified one of them as his son he had with Jihadi bride Sally Jones.

According to a report in the Daily Mail, the man said that his wife Sally Jones had fled to Syria to join Islamic State and took their son Jo Jo with her, who must have radicalised him later into executing ISIS prisoners.

Jones was declared as the world's most wanted terrorist by United Nations after she fled to Syria in 2013 with her 10-year-old son, Jo Jo.

"He was brilliant, just a normal boy – always chasing bugs, going down the park. I have had to block it out. It's been hard, we just have to carry on. It's disgusting he's been brainwashed," 13-year-old Jo Jo's father was quoted as saying.

In the video released by ISIS, Jo Jo can be heard referred to as 'Abdullah al-Britani'. Al-Britani is a term often used for terrorists hailing from Britain.

The video also shows five hostages, dressed in orange jumpsuits, kneeling on the ground as child terrorists stand behind them with guns in their hands.

The four other boys in the footage, apart from Jo Jo, are captioned as being Tunisian, Kurdish, Egyptian and Uzbekistani in origin. ISIS have often used children in their propaganda videos in which the militant group boasts about preparing the next generation of fighters.
