A government minister has been shot dead by his personal driver in Southern Sudan, an army official said.
Colonel Philip Aguer said that the driver then killed himself.
The cause of the shooting was not immediately clear but appeared unrelated to Southern Sudan's successful independence referendum from the north.
Aguer said the minister and his driver were believed to be related by marriage.
He declined to name the minister, pending notification of relatives.
The final results of Southern Sudan's independence referendum, held last month, were announced on Monday.
Nearly 99% of southerners voted for secession.
The oil-rich south is expected to become the world's newest nation on 9 July.
