Norway’s Refugee Council (NRC) reported that 38 million people are currently internally displaced worldwide, of which 2.8 millions are Iraqis and 6.7 millions are Syrian.
The report said more than 11 million people were displaced by violence in 2014 alone.
South Sudan, the Democratic Republic of Congo (DRC) and Nigeria follow Syria and Iraq in the number of people fleeing their homes due to violence and conflict.
“These are the worst figures for forced displacement in a generation, signalling our complete failure to protect innocent civilians,” said Jan Egeland, secretary general at the Norwegian Refugee Council (NRC).
International Organization of Migrants (IOM) said on Tuesday that the number of Iraqi people displaced due to the conflict in Iraq has reached 2.8m since the start of 2014.
Last month’s attacks by ISIS in Ramadi, the capital city of Anbar province, has caused the latest rise in the number of displaced people.
Clashes with ISIS militants in Anbar’s Ramadi have flooded southern Iraq with hundreds of thousands of refugees, while ISIS’s capture of Mosul along with continuing clashes in Kirkuk have led to another mass exodus to the Iraqi Kurdish Regional Government in the country’s north.
The Iraqi government has been criticised by displaced people for not being allowed to enter Baghdad. Thousands including children and women are outside of Ramadi.
The organisation said more than 133,000 people have left their homes in Ramadi and only 16,000 have returned.
Around 300,000 people were displaced internally in Iraq after ISIS launched an offensive throughout the country on June 9, 2014. The ISIS assault forced a huge number of civilians to leave their homes and flee to safer locations inside the country.
