An activist opposed to both IS and the regime of Syrian President Bashar al-Assad, who is well-known to the British business broadsheet, said he had “verified 100 executions” of foreign IS fighters trying to leave the jihadist group’s de facto capital.
IS fighters in Raqqa said the group has created a military police to clamp down on foreign fighters who do not report for duty.
Dozens of homes have been raided and many jihadists have been arrested, the FTreported.
Some jihadists have become disillusioned with the realities of fighting in Syria, reports have said.
According to the British press in October, five Britons, three French, two Germans and two Belgians wanted to return home after complaining that they ended up fighting against other rebel groups rather than Assad’s regime. They were being held prisoner by IS.
In total, between 30 and 50 Britons want to return but fear they face jail, according to researchers at the International Centre for the Study of Radicalisation at King’s College London, which had been contacted by one of the jihadists speaking on their behalf.
Since a US-led coalition began a campaign of air strikes against IS in August, the extremist group has lost ground to local forces and seen the number of its fighters killed rise significantly. There have been a string of apparent setbacks for IS in recent weeks.
Iraqi Kurds claimed on Thursday to have broken a siege on a mountain where Yazidi civilians and fighters have long been trapped.
The Kurdish advances came during a two-day blitz in the Sinjar region involving 8000 peshmerga fighters and some of the heaviest air strikes since a US-led coalition started an air campaign four months ago.
Meanwhile on Thursday, the Pentagon said several IS leaders had been killed in US air strikes.
In 40 days across October and November, some 2000 air raids killed more than 500 people, according to the Syrian Observatory for Human Rights, a Britain-based monitoring group, which relies on a network of sources on the ground.
