Foreign Secretary William Hague has today said a large number of Britons are fighting with ISIS, which has taken over huge parts of Iraq.
He told the Commons that about 400 UK nationals were involved in the conflict in Syria and some of them were fighting for the Islamic State in Iraq and Syria (ISIS).
Footage has emerged on internet, which appears to show an ISIS fighter questioning and killing Iraqi soldiers.
It comes after the insurgents, who have seized large swathes of territory in the past week, released graphic pictures purporting to show some of the 1,700 Shia soldiers they claim have shot dead near Tikrit.
According to a translation of the first clip, militants order their prisoners to chant the ISIS slogan “Baqiya”, which is thought to mean “(ISIS) will remain in existence” or “Islamic state will stay” reported Sky News
When asked where the government forces are, a soldier replies they have left.
The security deterioration in Iraq started last week when bloody clashes broke out between the Iraqi security forces and hundreds of gunmen who took control of several neighbourhoods in western part of Mosul and expanded later to other areas and provinces after the Iraqi security forces withdrew from the city.
