The spokesman for Ban Ki-moon said late Tuesday that the UN chief is alarmed by the July 11 attack on a compound popular with foreigners in Juba.
The Associated Press this week reported that South Sudanese troops went on a nearly four-hour rampage through the compound in one of the worst targeted attacks on aid workers in the country's three-year civil war.
Several witnesses told the AP that soldiers shot dead a local journalist while forcing the foreigners to watch, raped several foreign women, singled out Americans, beat and robbed people and carried out mock executions.
