A young boy at al-Hol refugee camp in Syria told a visitor that he wanted to join ISIS

A young boy at a Syrian refugee camp told a visitor that he wants to join ISIS and announced that he hopes to kill 'infidels'.

Talking cheerfully to a stranger, the boy revealed that he aspires to be an 'inghimasi' or suicide fighter.

The boy told the visiting journalist that he would target him if he was a 'kafir' or non-believer but promised not to kill the newcomer if he is a Muslim.

Footage of the conversation, filmed by journalist Mahmoud Shikhibra and shared on Twitter, was taken at the same al-Hol camp in northern Syria where British jihadi bride Shamima Begum was once a resident.

'I want to be Dawla', the boy says, using an Arabic term for ISIS.

Asked what that means, he uses the word 'inghimasi', a term defined by U.S. officials as a 'particularly lethal type of suicide bomber'.

An inghimasi is a fighter 'who seeks to cause as much death and destruction as possible prior to detonation', the Justice Department said when an ISIS supporter who wanted to be one was jailed earlier this year.

When the journalist suggests that the boy might want to be a doctor instead, the youngster insists: 'No, inghimasi'.

Asked what the suicide fighters do, the boy says: 'They kill'.

The al-Hol camp houses tens of thousands of displaced people including relatives of ISIS fighters and security fears have been on the rise.

In one incident, a woman was killed and six others injured in a section of the Kurdish-run camp that is reserved for foreign women.

Forty women from that sector were detained by security forces.

According to one source, ISIS women who had set up 'courts' to try their peers had stabbed to death a woman whom the camp's security personnel had been trying to rescue.

But local Kurdish news agency Anha gave a different account, saying that a gunfight had broken out after security forces had intervened in the area.

Mustafa Bali, spokesman for the Kurdish-led Syrian Democratic Forces (SDF) which led the ground offensive resulting in ISIS's military defeat in Syria earlier this year, warned earlier this week of worsening conditions the camp.

The situation is 'deteriorating sharply... ISIS militants have stepped up their regrouping efforts through women in the camp recently', he said.

'This is going to be very dangerous in future.'

The United nations said 'tensions remain high in the camp with security incidents reported on a weekly basis'.

In March, the SDF announced the defeat of the 'caliphate' which ISIS declared in 2014 over parts of Syria and Iraq, after the Kurdish-led force expelled the last jihadist fighters from a border village.

Tens of thousands of people, mostly women and children, were trucked to Kurdish-run camps in northeast Syria during the weeks-long campaign.

In total, some 12,000 foreigners - 4,000 women and 8,000 children - are now living in such camps, according to Kurdish authorities.
