(SKY news) BAGHDAD - Iraq's foreign minister urged neighbors to prevent "terrorists and killers" from crossing into his country and warned Sunday that the violence in Iraq could spill across its borders. Foreign Minister Hoshyar Zebari's comments came during the opening of a daylong conference that brought to Baghdad officials from all of Iraq's neighbors and other Mideast countries, as well as representatives from the U.N. and the Group of Eight industrialized nations. The first such conference in March saw the first direct U.S.-Iranian talks since the war began, focusing on border problems, Iraqi refugees and energy issues, including oil supplies.
