Cairo  - Groups of Bedouins protested Monday in Egypt's Sinai peninsula, blocking a main road, after Egyptian security forces opened fire, killing one man and wounding another, security sources said.

Police shot the two men when they refused to stop their car at a security check point, sources told the Deutsche Presse-Agentur, dpa. Bedouins often accuse Egyptian police of discriminating against them, including arresting Bedouins without charge.

Egypt has accused Sinai Bedouins of committing two terrorist attacks since 2004, using primitive explosive devices. The first bombing hit an upscale Taba resort, killing tourists and damaging the hotel building, and the second struck the Red Sea tourist resort of Sharm el-Sheikh.

The bombings damaged Egypt's tourism industry, a major source of income for the country. (dpa)
