Propaganda footage to emerge from the barbaric organisation shows a man sitting beside his three children issuing a call for Muslims on the idyllic islands of Trinidad and Tobago to rise up. In the video, a man, identified as Abu Zayd al-Muhajir, claimed he had fled his homeland because Muslims in Trinidad and Tobago were restricted in what they could do. He said people were free to wear the hijab or other Islamic clothing but that in reality Muslims were only allowed to practice what they were told.

He said: "The only practice that you can practice is what they tell you is halal [permissible] to practice.

I cannot sit and watch my children grow up in this land in which they cannot practice their Islam 100 per cent Abu Zayd al-Muhajir

"The other aspects of Islam are haram [forbidden] for you. "You cannot practice your deen [Islamic way of life] 100 per cent. "It was yearning for me that I knew I had to leave, I had to leave this land. "I cannot sit and watch my children grow up in this land in which they cannot practice their Islam 100 per cent."

TV6TNT.COM Abu Khalid converted from Christianity to Islam

Another fighter interviewed in the 11 minute film, Abu Khalid, said he had converted to Islam because of "the way the Muslims care about themselves, how they care about themselves, their family structure". He said he felt that he did not belong in Trinidad and that after reading sections of the Koran, he "started to understand that fighting is something that has been prescribed upon Muslims".

Abu Mansour al-Muhajir, another fighter from the twin island Caribbean country, said he had travelled to Syria to fight allies of the devil. He said: "Allah is inciting us to fight the friends of Satan for they are weak. "This is a time when the Prophet, Allah's peace and blessings be upon him, mentioned that there will come a time when all the nations of the world will gather around to wipe you out? "Who? The Muslim. As we speak today, over 60 nations of this world sign on to wipe out us, but Allah, Glorified and Exalted be He, is with us. "I hope and pray that Allah, Glorified and Exalted be He, will guide us and protect us and bring us to this land so that we will make jihad for this cause and to gain the reward of Allah, Glorified and Exalted be He."

Reports of Trinidadians making the trip to Syria to fight for ISIS first emerged last year when the island republic's former national security minister, Gary Griffith, claimed around 30 citizens were now terrorist fighters. The United Nations has also warned the country is being used as a recruiting ground for the terror group. It is not the first threat to the relatively peaceful Caribbean states from Islamic extremism.

Cyber hackers linked to the Islamist group twice attacked the government computers of Jamaica and St. Vincent and Grenadines over the summer. A top American general also warned earlier this year that 100 militants have already left Caribbean countries to fight with ISIS in Syria. Marine Gen. John F Kelly, chief of the US Southern Command, said extremists could potentially get across the US border when they return home. He added that small nations such as Jamaica, Trinidad and Tobago, and Suriname were concerned about fighters returning because they didn't have the resources to deal with the threat.
