Iraqis in Greece
The Iraqi Arabs who arrived in Greece are Muslims from the central and southern parts of Iraq, mostly Sunni with a tiny Shia minority. Sunni Arabs form 17 per cent of the total Iraqi population, which is almost an equal amount if not more than their Turkmen counterparts. Assyrians have a disproportionately large representation amongst Iraqis in Greece, this could be primarily because Greece has a Christian society, in which Iraqi Christians will find it easy to settle down in. Forming a quarter of the population in Greece, Iraqi Christians make up the majority of Christians from the Middle East, who arrived in Greece from the early 1990s.
Sectarianism
Pakistan, one of the largest Muslim countries the world, has seen serious Shia-Sunni sectarian violence. Almost 80 - 85 
of Pakistan's Muslim population is Sunni, and another 10 - 20% are Shia. However, this Shia minority forms the second largest Shia population of any country, larger than the Shia majority in Iraq.
