Turkish President Recep Tayyip Erdogan has accused German Chancellor Angela Merkel of supporting terrorists amid the ongoing Turkish pre-referendum rallies scandal with Europe.

Axar.az reports that earlier in the day, the German Foreign Ministry warned its nationals of potential security threats during the upcoming constitutional referendum in Turkey that would increase presidential powers over the legislature and the judiciary, scheduled for April 16.

“Unfortunately some countries of the European Union do not tolerate the rise of Turkey, and Germany is at the head. Germany relentlessly supports terrorism … Dear Merkel, you are supporting terrorists!” Erdogan said in Monday's interview with the A Haber and ATV channels.

Turkey had sent a list of organizations considered terrorist by Turkey with 4,500 files on their activities, he added, accusing Merkel of harboring terrorists in Germany without doing anything to correct the situation.
