Baghdad, Iraq (CNN) -- At least one civilian was killed and seven others wounded in a double roadside bomb attack in northern Baghdad Saturday night, an official at Iraq's Interior Ministry said.
The official said the bombs detonated in quick succession in Baghdad's Hurriya neighborhood and seem to have been targeting civilians.
In a separate incident, at least two rounds of indirect fire -- mortars or rockets -- hit the highly-fortified International Zone late on Saturday. There were no reports of casualties or damages.
Violence in Iraq has dropped drastically over the past two years, compared with the height of the sectarian war in 2006 and 2007, though attacks continue as leaders struggle to form a coalition government.
The United States recently ended its combat mission in Iraq, more than seven years after the U.S.-led invasion that toppled Saddam Hussein. Roughly 50,000 U.S. troops will stay in the country until the end of 2011 to train, assist and advise Iraqi personnel.
