A roadside bomb killed six people and wounded eight in Baghdad's western Amriya district today.
A police source said one of those killed was a child; he said the target of the bomb had been an Iraqi army patrol but that soldiers were not among the casualties.
Sunni insurgents fighting to topple the Shia- and Kurdish-led government attack Iraqi army and police patrols on a daily basis.
Yesterday, two policemen were killed when a roadside bomb went off near a police patrol in central Baghdad, and two Interior Ministry employees died when a bomb blast hit a ministry convoy.
The bodies of 18 men - bound, blindfolded and garroted - were found near Amriya, a Sunni insurgent stronghold, on Tuesday.
Officials have yet to confirm the religious identities of the 18 amid surging sectarian violence between minority Sunnis and majority Shias.
