Egyptian police have shot dead a Sudanese man attempting to cross the border illegally into Israel, Egyptian officials say

They say the man was shot south of the Rafah border crossing. The death brings to 20 the number of African migrants - seeking political asylum and jobs in Israel - killed at the border so far in 2008. Separately, an Egyptian policeman was killed by people traffickers - the third to die this year. Israel estimates that 2,800 people have entered the country illegally through its border with Egypt in recent years. Many are believed to be from Sudan, refugees from the civil war and the crisis in Darfur. Activists say they face economic marginalization and racism in Egypt.
