A Sudanese newspaper says a military spokesman has denied that the country's air force has bombed civilians in a southern province.
The independent Akher Lahza daily ran the report Saturday, one day after teachers said that a Bible school had been attacked.
The paper quoted Col. Sawarmi Khalid Saad as saying that reports of civilians being targeted were "Western plots" to damage Sudan's image.
Pictures obtained by The Associated Press on Friday showed two demolished buildings in the Nuba mountains in South Kordofan state. No one was reported to have been hurt or killed in the Wednesday attack.
U.S. ambassador to the U.N. Susan Rice said she was outraged by the "heinous" bombing.
The school was built by Samaritan's Purse, a North Carolina-based aid group.
