Hyderabad, India

WHEN the Islamic State in Iraq and Syria (ISIS) identified a promising young recruit willing to carry out an attack in one of India's major tech hubs, the group made sure to arrange everything down to the bullets he needed to kill victims.

For 17 months, terrorist operatives guided the recruit, a young engineer named Mohammed Ibrahim Yazdani, through every step of what they planned to be ISIS's first strike on Indian soil.
