Guideline 5.0 - Legal
In distributing apps on the App Store, Apple must comply with U.S. laws. Under U.S. sanctions regulations, the App Store cannot host, distribute, or do business with certain apps or developers connected to U.S. embargoed countries or regions.
We have recently identified that Apple may not host your app because doing so would be prohibited by U.S. sanctions regulations. Unfortunately, therefore, we are unable to include your app on the App Store at this time.
