THE HAGUE, Netherlands (AP) — Armenia is accusing neighboring Azerbaijan of systematically promoting ethnic hatred against Armenia citizens as the two nations that fought a six-week war last year face off at a U.N. court. Armenian representative Yeghishe Kirakosyan made the accusation Thursday as a hearing opened at the International Court of Justice in The Hague. Azerbaijan rejected the claim and urged the court to reject it. Armenia has asked the court to impose urgent interim measures to prevent Azerbaijan breaching an international convention to stamp out ethnic discrimination. The case stems from longstanding enmity that boiled over into last year’s war over the disputed region of Nagorno-Karabakh that left more than 6,600 people dead.
