As ISIS loses ground to coalition-backed forces, foreign fighters are running away – hoping to get away from the final battles set to take place around besieged cities, including Raqqa.
At least two British fighters have attempted to enter Turkey in recent weeks, along with an American.
Guardian sources claimed the foreign fighters gave themselves up after spending two years in ISIS controlled areas.
Reports suggest dozens more have also attempted to escape the exodus in Syria.
Turkish officials said one Brit was caught at the Kilis crossing in southern Turkey where he surrendered to police. He was reportedly with his British wife.
The group was also said to be with two Egyptian women who had lost their husbands in the conflict.
A spokeswoman for the UK Foreign and Commonwealth Office said: “We are in contact with the Turkish authorities following the detention of a British man on the Turkey/Syria border.”
Although the British woman was released, the British and American men could be charged and jailed.
The US citizen’s mother has been interview about her son and claimed he had arrived in Syria after marrying a woman from the country.
She claims he wanted to help with the humanitarian efforts and moved his three children there.
According to the family he had claimed to be in contact with US officials in Turkey where he planned to escape to.
Embassies in Turkey and Europe have claimed they have been contacted by an increasing number of people looking to return from Syria.
It is feared some may be using the mass break-up of the group to flee back to Europe and committee atrocities.
Shiraz Maher, deputy director of the International Centre for the Study of Radicalisation at King’s College said: “Europe has to keep its guard up.
“The threat will likely become more acute in the coming months and years as the pressures on Islamic State intensify.”
It is not clear how many have been able to return without detection.
Masrour Barzani, chancellor of security for the Kurdistan Regional Government in northern Iraq, said: “The nature of the fight against Isis will change into an intelligence war.
“Defeating Isis militarily deprives them of territory and prevents them attracting and recruiting foreign fighters.
“This in turn discourages foreign fighters from staying in the so-called Islamic State and they will eventually try to escape or surrender.
“However, the threat foreign fighters can still pose upon returning to their countries should not be underestimated.”
