Britain and the United States announced that four Sudanese were named for United Nations sanctions over war crimes in Darfur, but Russia and China signalled disapproval. The four, reduced from a longer British list, are one Sudanese government official, one pro-government militia member and two rebel leaders, UN diplomats said.John Bolton, the US ambassador to the UN, told reporters on Wednesday that a 48-hour silence procedure kicked in to secure required unanimous approval by all 15 council members of the list of four deemed to be impeding the peace process and violating international human rights law. The list was submitted more than a year after the council adopted Resolution 1591, which authorises measures against people committing atrocities or undermining peace efforts in Sudan's western region. Bolton said the fact that only four people were named did not mean that others would not be considered. "The investigation and consideration of other individuals continue," he said.
