Elsewhere, a suicide bomber killed six policemen, while insurgents killed an Egyptian in continued violence, police said yesterday. "Hammuda Ahmed Adem, an administrative employee at the Sudanese Embassy, was killed by armed men who intercepted his car in the Mansur area," a source said.Adem was rushed to the Yarmuk hospital but died before he could be treated, an embassy source later said.
