There is a small number of Syrian Refugees who are going to Iraq, but this is usually a movement in transit. Iraq is currently involved in much the same civil war that Syria is, so the people are not staying there.
If you count those staying in Iraqi Kurdistan, the number jumps quite substantially with roughly 250,000 registered.
The answer used to be Syria. However, given the Syrian Civil War, many Iraqi refugees have fled Syria. Jordan is probably a better answer now, even though it lacks a large number of Iraqi refugees.
3,000,000 were left as refugees
Generally, continuous war-conditions (and in the cases of Syria and Sudan, genocide) have caused refugees to be displaced.
Many Iraqi refugees have fled to Syria and Jordan (although those who fled to Syria are now turning back around). Those that could go farther have found asylum in the United States and much of Western Europe.

During World War 2 the Vatican took in many refugees and hid them from the Nazis. Recently (2015) they took in a few refugee families from Syria.
Historians estimate approximately one million Vietnamese refugees left Vietnam.
Syria is in civil war and millions are fleeing the country. Syria is in the Middle East/Asia.
There are currently thousands of refugees attempting to flee Syria. Many countries has expressed willingness to accept refugees from the conflict including NATO countries and some muslim countries.
As of 2017, Turkey has the most Syrian refugees with 2.7 million. Turkey borders Syria to the north.
I think I recall, from network TV news, that Syria has now closed its borders to Iraqi refugees.
