"Welcome to Syria, you mutt": Surviving hostage testifies about ordeal in ISIS captivity

Federico Motka's abductors greeted him in English after he and his colleagues were kidnapped near a refugee camp on the Turkish border: "Welcome to Syria, you mutt."

For the Italian aid worker, it was the beginning of 14 months of brutality at the hands of the Islamic State.

Motka testified about the ordeal Thursday at the terrorism trial of El Shafee Elsheikh, a British national charged with taking a leading role in an Islamic State kidnapping scheme that took more than 20 Westerners hostage between 2012 and 2015.
