Iraqi police say a drive-by shooting and a roadside bomb have killed a motorist and a government official in Baghdad.

Police say the off-duty Interior Ministry official was killed Friday midday when gunmen sprayed his car with bullets as he was driving. They say that an hour later, a roadside bomb hit a pickup truck on another main street, killing the driver and wounding two passengers.

The officials spoke on condition of anonymity because they were not authorized to talk to reporters.

Violence has diminished in Iraq since a wave of sectarian bloodshed in 2006 and 2007, but insurgents carry out frequent attacks on security forces and civilians, trying to undermine the Shiite-led government. It has been deadlocked by sectarian quarrels since the U.S. pulled its troops out last December.
