Turkish Ambassador to the U.S. Namik Tan expressed dissatisfaction with U.S. President Barack Obama’s address to the Armenian American community on April 24.

“The U.S. President’s address is a historical mistake, inadequate and one-sided political language,” Tan posted on Twitter.

“One-sided comments on historical facts do not contribute to establishment of peace and accord between the parties. The U.S. should encourage the Armenian-Turkish normalization, but not hamper it with similar statements,” Samanyolu quoted Tan as saying.
