Pocar was addressing the United Nations Security Council on Thursday, submitting a report on the tribunal's completion strategy.
He underlined that the Hague tribunal could not close its doors before Karadzic and Mladic, on the run for 10 years, were brought to justice. He said the tribunal was nonetheless committed to its strategy to complete working in 2010.
Chief prosecutor Carla del Ponte, who submitted a report on the work of her office, told the press the Hague tribunal would not complete its work before trying Karadzic and Mladic.
Del Ponte said the Office of the Prosecutor was preparing the referral of cases in which no one had been indicted yet to courts in Croatia, Serbia-Montenegro, Macedonia, and Bosnia-Herzegovina. She added it was up to national courts to decide whether to complete investigations and indict someone.
Pocar said that one case with two indictees had already been referred to Croatia, two had been referred to Bosnia, while it was yet to be decided on requests by the Office of the Prosecutor to refer to national courts another 12 cases with 20 accused.
Both Pocar and del Ponte said that apart from Karazic and Mladic, it was important to arrest another four of six fugitive indictees from Republika Srpska and Serbia-Montenegro.
Del Ponte said Karadzic, Mladic and another three indictees were within the reach of the authorities in Republika Srpska and Serbia-Montenegro, and that one was hiding in Russia.
