Sudanese warplanes bombed Christian villages in the Nuba Mountains during the Christmas season.

Eleven Christians died in the attacks that took place between Dec. 18-26.

The Arabic-Islamic regime in Khartoum has long targeted residents of the Nuba Mountains, who are mostly Christian and black Africans.

Thousands of non-Arab Sudanese are hiding in caves in the mountains. One church leader said they are praying and waiting for the international community to intervene.
