Sources told NDTV the ISI has been planning this attack - on the Ram Temple - for some time, and that it included working for the past 10 months with the Islamic State-Khorasan Province, a regional branch of the Islamic State that is believed to be active in south-central Asia.
Rehman was reportedly trained by an ISKP module; this included indoctrination and training videos administered via a video call while he was monitoring his father's meat shop.
The conspiracy to attack the Ram Temple was triggered last week.
