( CNN ) -- Sudanese President Omar al-Bashir , wanted for crimes against humanity by the International Criminal Court , arrived in Libya Saturday to visit with the country 's post-Gadhafi leaders . Libya 's National Transitional Council will use the one-day visit by al-Bashir to discuss `` unsettled matters '' between the two countries , NTC member Mohammed al-Sayeh told CNN . During the uprising in Libya , Moammar Gadhafi hired mercenaries who came from the Darfur area in Sudan to the Libyan border , al-Sayeh said . As the conflict tilted in favor of the rebels , al-Bashir tried to stop mercenaries from coming through and gave the Libyan rebels some guns and tanks , he said . There is also the issue of illegal immigration from Sudan into Libya through the country 's southern border , al-Sayeh said . `` We had a lot of unsettled matters that we had to discuss with President Bashir , '' he said . Libyan authorities , however , have no intention of handing al-Bashir over to the International Criminal Court , where he is wanted for crimes committed in Darfur . Gadhafi , who the Libyan rebels killed after capturing , was also wanted by the ICC . The new Libyan authorities said they are willing to work with the ICC on cases involving Libyans . Richard Dicker , Human Rights Watch 's director of the international justice program , said by not turning over al-Bashir to the court , it breaks the spirit of cooperation with the ICC . `` Welcoming to their capital a head of state accused of genocide , crimes against humanity , and war crimes is deeply disturbing in what it suggests about the new Libyan authorities ' commitment to human rights and the rule of law , '' Dicker said . CNN 's Jack Maddox and Mariano Castillo contributed to this report .
