Turkey has expressed "deep regret" over U.S. President Barack Obama’s April 24 statement commemorating the Armenian Genocide, according to RFE/RL.

Obama described the event as "one of the worst atrocities of the 20th century."

The U.S. leader also said the Armenians were "brutally massacred or marched to their deaths," but he did not use the word "genocide."

Turkey's Foreign Ministry described Obama's remarks as "biased" and a distortion of "historical facts."
