BBC News - Syria refugees pour into Iraqi Kurdistan in thousands
Up to 10,000 crossed at Peshkhabour on Saturday, bringing the total influx since Thursday to 20,000. The UN says the reasons are not fully clear.
The UN agencies, the Kurdish regional government and NGOs are struggling to cope, correspondents say.
This is one of the biggest waves of refuges in the region for a long time and will no doubt bring more instability in an already unstable region. Syria has been at a steady boil for the past year and is starting to boil over and I think western intervention may be needed to prevent this conflict spreading into other regions.
