On the Kreator official Facebook Page:
Kreator Tour Manager here. Unfortunately due to Greek Customs officers, we were not able to leave Greece on time to make it to Istanbul. We would like to mention that the promoters, Mood Productions, did everything to help save the show. Please check their website to see information on ticket refunds. Announcement will be made soon. www.mood-pro.com
Kreator-Mille: We tried all efforts to make it happen, however in the end this was not possible. We are working to reschedule a date for the summer time. Thanks for your support.
