YEREVAN, Armenia (AP) — Armenia’s leader is praising President Joe Biden’s recognition of the deaths of 1.5 million Armenians under Ottoman Turkish rule as genocide, calling it “a powerful step.” Biden’s announcement Saturday and Prime Minister Nikol Pashinyan’s response came as Armenians streamed to a hilltop memorial to lay flowers and mourn the victims.

But Pashinyan said it “reaffirms the supremacy of human rights and values in international relations.
