According to the Home Ministry source, all four were deported from the UAE for posting pro-ISIL comments on Facebook. They allegedly had been in contact with young people in India with the aim of recruiting them into the terrorist organization.
The detainees used international WhatsApp numbers for their recruitment purposes. The Islamic State flag and related content was supposedly sent over the messenger to an account.
The top Indian intelligence agencies, the National Intelligence Agency, the Research And Analysis Wing and the Kerala State Police are all interrogating the four Indian nationals.
According to local reports, the detainees are part of a group of 11 suspected ISIL sympathizers from India, who were detained by UAE authorities in late August on charges of planning to join the Islamic State or recruiting young people into the terrorist organization.
