Hi bigopie,
I have had a look at these articles and all I can gather is that they come from a disgruntled government employee. They stem from the Kurdistan region. They are referring to the Kurdistan Central Bank. There is no evidence the Central Bank of Iraq or the Kurdistan central Bank has suspended dealings with Warka Bank.
However, I will be keeping an eye out for future information on this matter. But at this point, I really find no credence in it.
