In this Friday, Oct. 25, 2013 photo, Mohammed Siddeh, 52, at his workshop in Russeifa, outside Amman, Jordan, holds a picture of his son, Abdullah Siddeh, with the boy's name inscribed on the print in Arabic. Abdullah blew himself up in a rebel attack on a police station in Syrian capital of Damascus at the age of 17. Abdullah left his home in December, 2012, without telling his parents. He surfaced in Syria a few days later, where he joined Jabhat al-Nusra. (AP Photo/Manu Brabo)
