The South African military is withdrawing about 50 peacekeepers from a United Nations mission in Congo because they violated disciplinary codes, a military spokesman said Thursday. The violations included leaving a base after curfew, Brig. Gen. Xolani Mabanga said. The troops were deployed in eastern Congo as part of a unit with a mandate to fight rebel groups there, according to a South African military statement. The statement said the personnel compromised the security of other South African troops and will face military prosecution. It said they violated not only the South African military conduct codes but also those of U.N. peacekeepers.
