Sunni Arab extremists have begun a systematic campaign to assassinate police chiefs, police officers, other Interior Ministry officials and tribal leaders throughout Iraq, staging at least 10 attacks in 48 hours.

Eight policemen have been killed, among them the police chief of Baquba, the largest city in Diyala Province. Two other police chiefs survived attacks, though one was left in critical condition, and about 30 police officers were wounded, according to reports from local security officers.
