The names of six Indians killed after joining the Islamic State (Isis) were released on Monday by Indian security agencies.

The list contains the names of men from Karnataka, Maharashtra, Telangana and Uttar Pradesh.

Three of the terrorists of the Islamist group in Syria were natives of Karnataka. The rest were from Maharashtra, Telangana and Uttar Pradesh. 

Two of the Isis recruits were from Bengaluru.

According to the intelligence report, the two dead fighters from Bengaluru have been identified as Mohammad Umar Subha, a resident of Shivaji Nagar, and Faiz Masood from Cooke Town.

A third Karnataka man, who has died in Syria, has been identified as Maulana Abdul Kadir Sultan Armar from Bhatkal.

The other slain Isis recruits have been identified as Athif Vaseem Mohammad from Adilabad in Telangana, Saheem Farooque Tanki from Thane in Maharasthra and Mohammad Sajid from Azamgarh in Uttar Pradesh.

It is reported that at least 23 Indians are currently in Syria, fighting for the radical Muslim group. 

The intelligence report, which was prepared by foreign agencies and shared with Indian security personnel said that the Isis recruits from India, Pakistan, Bangladesh, Nigeria and Sudan are considered inferior to Arab fighters by Isis.

The intelligence report also noted that there is a disproportionately high level of casualty among the South Asian and African as often these "so-called inferior fighters" are tricked into taking up suicide missions.

According to PTI, they are given an explosive-laden vehicle and asked to go near a targeted destination, from where they are asked to call a certain number.

They are told that after the call, somebody will meet them to explain the mission. But when they dial the number, it triggers the timer of the bomb to explode.
