Nine people were killed on Saturday in attacks north of Baghdad, including a suicide car bombing

Nine people were killed on Saturday in attacks north of Baghdad, including a suicide car bombing, the latest in a spate of violence in Iraq.
  
Saturday's violence struck in the main northern city of Mosul, where a suicide attacker set off a vehicle rigged with explosives near a police patrol on the city's southern outskirts. The explosion killed four people including a policeman, police and medical officials said.
  
And in the ethnically mixed town of Tuz Khurmatu, which lies at the heart of the area disputed between the Kurds and Baghdad, gunmen opened fire on another police patrol, killing three policemen and wounding a fourth, security and medical officials said.
  
The tract of land, which the Kurds want to incorporate over the objections of Baghdad, stretches from Iraq's eastern border with Iran to its western frontier with Syria.
  
In the city of Tikrit, militants fired on day labourers waiting near a grain silo, killing two and wounding four, officials said.
