MOSUL, Iraq - A suicide bomber blew himself up inside a Shiite mosque during a funeral Thursday in the northern city of Mosul, killing at least 30 people, witnesses and hospital officials said, hours after gunmen killed two district police chiefs in Baghdad. Meanwhile, Iraq's main Shiite party and a Kurdish bloc have reached a deal that sets the stage for a new government to be formed when the National Assembly convenes next week, officials from both sides said Thursday.
