Thousands of Syrian refugees poured into northern Iraq "in a sudden, massive movement", the United Nations said.
On Friday, a spokesman for the UN High Commissioner for Refugees said:
Kurdistan remains relatively safe and stable, however tensions are increasing in view of the forthcoming elections and also to do with other domestic factors there. This does have impact on our (aid) delivery programme in Iraq, but nonetheless it is the region where most refugees have come into.
Overall the flow of Syrian refugees has dropped sharply since a peak earlier this year when 5,000 to 8,000 crossed every day into neighbouring countries, according to the UN.
