Turkish President Recep Tayyip Erdogan on Thursday warned that the German parliament's recognition of World War I killings of Armenians by Ottoman forces as genocide would "seriously affect" bilateral ties.

"The resolution adopted by the German parliament will seriously affect relations between Germany and Turkey," Erdogan said, confirming that Ankara has recalled its ambassador to Germany for consultations.

Germany's charge d'affaires in the capital has also been summoned to the Turkish foreign ministry later in the day, a spokesperson for German embassy in Ankara told AFP.
