Turkey shares the pain of Armenians whose parents or grandparents were killed under the Ottoman Empire during World War I, Prime Minister Ahmet Davutoglu said on Monday.

"We once again respectfully remember and share the pain of grandchildren and children of Ottoman Armenians who lost their lives during deportation in 1915," Davutoglu said in a statement released by his office to mark the 100th anniversary of the tragedy.

Armenians consider the mass killings a genocide, a term Turkey refuses to recognise.
