THE HAGUE, Netherlands (AP) -- A top Ukrainian diplomat called Russia a "terrorist state" Tuesday as he opened his country's case against Moscow at the United Nations' highest court, and lawyers argued that Russia bankrolled a "campaign of intimidation and terror" by rebels in eastern Ukraine in 2014.
Anton Korynevych was addressing judges at the International Court of Justice in a case brought by Kyiv against Russia linked to Moscow's 2014 annexation of the Crimean Peninsula and the arming of rebels in eastern Ukraine in the years before Russia's full-scale invasion in February 2022.
Ukraine wants the world court to order Moscow to pay reparations for attacks in the regions, including for the downing of Malaysia Airlines flight MH17 that was shot down by Russia-backed rebels on July 17, 2014, killing all 298 passengers and crew.
"When it could have instructed its officials not to fund groups committing violence against, Russia did nothing," Harold Koh, a lawyer for Ukraine, told judges. "Instead, as more deadly weapons arrived in Ukraine and more Ukrainian civilians suffered atrocities, Russian officials escalated their illegal supply of monies and weapons sending."
Koh said that in July 2014, a Buk anti-aircraft system was sent into Ukraine "after which Malaysia Airlines Flight MH17 was destroyed."
Earlier, Korynevych said that with Moscow unable to beat Ukraine on the battlefield, "it targets civilian infrastructure to try to freeze us into submission. Earlier today, just today, … Russia blew up a major dam located in Nova Kakhovka, causing significant civilians evacuations, harsh ecological damages and threatening the safety of the Zaporizhzhia nuclear power plant. Russia's actions are the actions of a terrorist state, an aggressor."
Four days of hearings in the court's ornate, wood-paneled Great Hall of Justice opened against a backdrop of Europe's deadliest conflict since World War II. Ukraine and Russia are trading accusations of blame for the damage to the Kakhovka dam and hydroelectric power station, which are located in a part of Ukraine that Moscow controls.
Meanwhile, in The Hague, lawyers for Kyiv were presenting legal arguments to support their case Tuesday, followed by Russia on Thursday. Each side has another opportunity next week to present evidence. Judges are expected to take months to issue a judgment.
Another lawyer on Ukraine's team, David Zionts, said that pro-Russia forces in eastern Ukraine "attacked civilians as part of a campaign of intimidation and terror. Russian money and weapons fueled this campaign."
The case is one of several legal proceedings against Russia linked to Ukraine.
In a separate case brought by Ukraine in the immediate aftermath of Russia's illegal invasion, the world court issued a preliminary order calling on Russia to stop hostilities -- a legally binding ruling that Moscow ignored.
In that case, Kyiv is arguing that Russia violated the 1948 Genocide Convention by falsely accusing Ukraine of committing genocide and using that as a pretext for the Feb. 24, 2022, invasion. Moscow argues that the court doesn't have jurisdiction.
Not far away at the International Criminal Court, judges have issued an arrest warrant for Russian President Vladimir Putin on charges of deporting and illegally transferring children from Ukraine. Russia isn't a member of the court and doesn't recognize its jurisdiction.
Meanwhile, a Dutch domestic court last year convicted two Russians and a pro-Moscow Ukrainian for their roles in downing MH17 and sentenced them in their absence to life imprisonment. Ukraine also has another case against Russia at the International Court of Justice over its invasion, and the Netherlands and Ukraine are suing Moscow at the European Court of Human Rights over MH17.
Russia has always denied involvement in the downing of the passenger jet that was flying from Amsterdam to Kuala Lumpur when it was shot down by a Soviet-era missile over eastern Ukraine.
Tuesday's hearing is in a case Kyiv brought in 2017 related to Russia arming rebels in eastern Ukraine and restricting the rights of ethnic Tatars and other minorities following its annexation of Crimea in 2014.
"The Russian Federation has contempt for international law," Korynevych said. "Over the last 16 months, the world has woken up to this dark reality."
