The Hague - The International Court of Justice (ICJ) was to say Tuesday whether it has jurisdiction to rule on a claim by Croatia that Serbia committed genocide against its population in the 1991-95 war.
Croatia had filed the case against the rump Yugoslavia, consisting of Serbia and Montenegro, in 1999, while it was still run by the strongman Slobodan Milosevic.
Zagreb claims Belgrade fomented and supported a Serb insurgency following Croatia's declaration of independence from Yugoslavia in 1991.
Ethnic Serbs, then making up some 12 per cent of the population, had proclaimed a state of their own, which was recognized only by Belgrade, on a third of Croatia's territory.
