THE HAGUE, Netherlands (AP) — Armenia accused neighboring Azerbaijan of systematically promoting ethnic hatred against Armenia citizens, as the two nations that fought a six-week war last year faced off at a U.N. court on Thursday.

Armenian representative Yeghishe Kirakosyan made the accusation as a hearing opened at the International Court of Justice into a request by Armenia for judges 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. The region is within Azerbaijan but had been under the control of ethnic Armenian forces backed by Armenia since the end of a separatist war in 1994.

Kirakosyan said Armenia wasn't asking the court to rule on the root causes of the war, but “seeks to prevent and remedy the cycle of violence and hatred perpetrated against ethnic Armenians."

Lawyers representing Azerbaijan were scheduled to address the court later Thursday. Azerbaijan also has filed a similar case alleging discrimination against its citizens by Armenia and also has requested the world court to impose interim measures. Hearings in the Azerbaijan case are scheduled to start next Monday. Rulings on both requests will likely be issued in coming weeks.

Both nations' cases alleging breaches of the International Convention on the Elimination of All Forms of Racial Discrimination will likely take years to reach their conclusion at the Hague-based court.

Last year’s conflict ended when Armenian Prime Minister Nikol Pashinyan signed a Russia-brokered cease-fire agreement that granted Azerbaijan control over parts of Nagorno-Karabakh as well as adjacent territories occupied by Armenians.

Armenia says more than 3,700 Armenians and Nagorno-Karabakh residents died in the war. Azerbaijan said it lost 2,900 people.

Kirakosyan told the court that despite the deal that ended last year's conflict, “Azerbaijan continues to espouse and actively promote ethnic hatred against Armenians.”

He said that Azerbaijan has “captured, tortured, and arbitrarily detained numerous members of Armenian armed forces and civilians of ethnic Armenian origin” and “continues to destroy Armenian cultural heritage and religious sites or negate the Armenian character, and the territory’s economic controls.”
