The US President has formally recognised the murder of an estimated 1.5 million Armenians by the Ottoman Empire as genocide. The concession, which Mr Biden made as a presidential proclamation, had reportedly been planned in advance.
Mr Biden purportedly communicated his intentions of making a proclamation to Turkey’s President Recep Tayyip Erdogan during a phone call on Friday.
The US President said: “Each year on this day, we remember the lives of all those who died in the Ottoman-era Armenian genocide and recommit ourselves to preventing such an atrocity from ever again occurring.
“Beginning on 24 April 1915, with the arrest of Armenian intellectuals and community leaders in Constantinople by Ottoman authorities, one and a half million Armenians were deported, massacred, or marched to their deaths in a campaign of extermination.
“We honour the victims of the Meds Yeghern so that the horrors of what happened are never lost to history.
“And we remember so that we remain ever-vigilant against the corrosive influence of hate in all its forms.”
Turkey responded to Mr Biden’s statement, accusing him of basing his judgement “solely on populism”.
Turkish Foreign Minister Mevlut Cavusoglu said Ankara “entirely rejects” Mr Biden’s statement, while Turkey’s foreign ministry announced it called the US Ambassador to a summit.
Mr Cavusoglu wrote in a tweet: “‘Words cannot change or rewrite history.’
“We have nothing to learn from anybody on our own past.
